Is Everything For Sale? The Hidden Cost of Letting Markets Run Our Lives

When we started treating every problem as something that money could fix, we quietly crossed a line we never voted on. Here's why that matters — and why it's harder to undo than you think.

Political Philosophy Market Society Civic Life ~2000 Words

There's a quiet question that has been building under the surface of modern life — one we rarely state out loud: Should everything be for sale? Not just consumer goods or luxury experiences, but the fundamental structures of how we live together. Healthcare access. Political influence. Education. Even a spot in a line. Once you start looking, it's everywhere.

Consider a detail that might surprise you. In Santa Barbara, California, if you're serving a jail sentence and you dislike the standard accommodations, you can pay $82 a night for a cell upgrade. Not a hotel. A jail. At theme parks across the United States, you can pay extra for a "fast track" ticket that lets you skip the queue that everyone else has waited in for hours. And in Washington, D.C., lobbyists routinely hire line-standing firms — who in turn hire homeless individuals and low-income workers — to hold their place at congressional hearing queues overnight. When the hearing begins, the lobbyist walks in and takes the front seat.

These examples might seem like harmless quirks of a prosperous society. But they are symptoms of something much larger — a transformation in how we think about what markets are supposed to do.


Market Economy vs. Market Society: A Crucial Difference

There is a meaningful distinction between a market economy and a market society — and it's one that deserves far more attention than it gets.

A market economy is a tool. It is, arguably, a powerful and effective tool for organizing productive activity, allocating resources, and generating prosperity. Virtually every modern society uses it in some form, and there are good reasons why. When prices reflect scarcity and demand, resources tend to flow where they are needed. Innovation gets rewarded. People have incentives to work, create, and exchange.

A market society is something different entirely. It is a way of life in which market values — the logic of buying, selling, pricing, and efficiency — begin to govern not just the economy, but every domain of human experience. Personal relationships. Family decisions. Healthcare. Civic participation. Education. Law. In a market society, the first question asked of anything is: What is it worth? What will someone pay for it?

Over the past three decades, we have drifted — almost without realizing it — from having a market economy to becoming a market society. And we never really voted on whether that was the kind of society we wanted.

That drift has happened gradually, through thousands of small decisions, policy changes, and cultural shifts. The outsourcing of military functions to private contractors is one stark example. During the wars in Iraq and Afghanistan, private military contractors on the ground actually outnumbered U.S. military troops. No public debate preceded this. No one asked voters whether they believed that the task of fighting wars should be marketized. It simply happened — driven by ideology, convenience, and powerful interests.


Two Reasons to Worry

1. Inequality Bites Harder When Everything Is for Sale

The first concern is about what it means to be unequal in a marketized world. When the things that money can buy are limited to yachts and vacation homes, inequality is uncomfortable but perhaps tolerable. The rich have more luxuries. Others do not. But the essential goods of life — decent health, a good education, a voice in democratic decisions — remain broadly accessible.

But when money begins to govern access to those essentials too, the picture changes dramatically. When the best medical care is reserved for the wealthy. When elite education requires not just talent but the right connections and resources. When political influence in campaigns can simply be purchased. The marketization of everything sharpens the sting of inequality — it turns what might have been a difference in lifestyle into a difference in life itself.

$82 Per night

Cost of a "cell upgrade" at Santa Barbara County Jail — market logic applied to incarceration.

$50 Cash per grade "A"

Incentive offered to students in NYC and Chicago schools to boost academic performance.

$2 Per book read

Dallas program paid 8-year-olds to read books — children read more, but chose shorter ones.

This is not a hypothetical. The social and civic consequences of a fully marketized society are already visible. When the affluent and those of modest means increasingly live in separate neighborhoods, send their children to different schools, receive different qualities of healthcare, and inhabit entirely different worlds — the social fabric begins to fray.

2. Markets Can Corrupt the Goods They Touch

The second concern is subtler — and in some ways more troubling. It has to do with whether markets change the meaning and character of the things they enter.

Economists tend to assume that markets are neutral. That whether you receive a flat-screen television as a gift or purchase it with cash, the television remains the same object. And for material goods, this is largely true. But for non-material goods — social practices, relationships, civic institutions — the assumption breaks down.

Consider the debate over paying children cash incentives to study or read books. Some cities tried exactly this. In New York, Chicago, and Washington, D.C., children were offered $50 for an A and $35 for a B. In Dallas, 8-year-olds received $2 for each book they read. The results were instructive. Cash incentives for grades produced mixed and largely disappointing outcomes. The book payment did lead children to read more — but they chose shorter books. And the deeper worry remained: were these children now learning that reading is a form of piecework? That knowledge is a transaction? That the only reason to engage with ideas is money?

The Core Anxiety: If children grow up believing that learning is something you do because you're paid to do it, what happens to curiosity? What happens to the love of reading — the kind that sustains people through life, that fuels intellectual culture, that builds democratic citizens? Once a cash incentive teaches the wrong lesson, can it be unlearned?

This is not a trivial concern. When market mechanisms enter domains where other values — intrinsic motivation, love of knowledge, civic duty, loyalty, care — were previously doing the work, they don't simply add an economic layer. They crowd out the non-market values. They change what the activity means. And once changed, it is very hard to restore.


The Cash Incentive Debate: A Useful Test Case

The debate over paying students is a microcosm of the larger question. Those who favor it make a pragmatic argument: it works at the margins, it's measurable, and if it gets disadvantaged children into the habit of reading or studying, perhaps that's enough of a start. Let them fall in love with learning later. The initial incentive is just scaffolding.

Those who oppose it worry about exactly what that scaffolding teaches. The intrinsic motivation to learn — the genuine curiosity, the sense that books and ideas are worth engaging with because of what they offer — is not just a nice-to-have. It is the foundation of everything that education is supposed to produce. When you replace it with cash, you may be building on sand.

Position Core Argument Risk Acknowledged
Pro-Incentive Cash jump-starts behavior; empirical results matter; habit formation can follow. May need follow-through programs to transition students from extrinsic to intrinsic motivation.
Anti-Incentive Intrinsic motivation is the real prize; paying for learning corrupts its meaning. Doesn't offer an equally scalable alternative for disadvantaged students immediately.
What the Evidence Showed Cash for grades: mostly ineffective. Cash for books: more books read, but shorter ones chosen. Long-term effects on love of reading remain unknown and deeply uncertain.

Neither position is obviously wrong. But the debate itself reveals something important: the moment you introduce a cash incentive into a domain like education, you have already changed the question being asked. No longer is the question "What does it mean to be educated?" — it becomes "What behavior can we produce for a given price?"


The Corrosion of Commonality

Perhaps the deepest problem with a fully marketized society is what it does to the sense that we are — in some meaningful way — all in this together.

Democracy does not require perfect equality. It never has. But it does require something: that citizens share in a common life. That people from different backgrounds, different social classes, different walks of life actually encounter one another in the ordinary course of living. This is not sentiment. It is a practical necessity. The shared spaces of civic life — schools, parks, public transportation, even waiting in lines — are where we learn to negotiate with people who are not like us. Where we develop the capacity to abide differences. Where we discover, against our tribalist instincts, that we have a stake in the common good.

When the affluent can buy their way past every queue, every crowd, every shared experience — they remove themselves from the common life. And in doing so, they impoverish it for everyone, including themselves.

Think about what the "fast track" ticket at an amusement park actually signals. It is not merely a convenience purchase. It is a symbol of a world where the experience of waiting — of sharing the same time in the same line — has been made optional for those who can afford to leave it behind. Individually, it seems trivial. Systematically, it teaches a lesson about who belongs in the common life and who has transcended it.

The same logic extends to every domain touched by marketization. Separate healthcare tiers. Private schools versus under-resourced public ones. Gated communities. Business-class airports with their own separate lounges, boarding lanes, and security queues. Each of these is a small act of exit from shared public life. Accumulated over decades, they amount to a wholesale withdrawal of the affluent from the common institutions that democratic society depends on.


What We Need to Debate — and Why We Don't

To resist the marketization of everything, we need to do something our culture finds increasingly difficult: reason together in public about the value and meaning of the social practices we prize. We need to ask, openly and rigorously, where markets belong — and where they don't. Where efficiency and pricing are the right tools, and where they crowd out something more important.

This is hard because these questions are genuinely contested. They involve deep disagreements about values, about the good life, about what we owe one another. And our public discourse has, over the past three decades, become increasingly uncomfortable with exactly this kind of moral reasoning. We have retreated into a thin proceduralism — respecting individual choices, maintaining neutrality on questions of value — that cannot accommodate the depth of what is actually at stake.

The result is that market logic expands into the vacuum. In the absence of a robust public debate about what money should and should not buy, the default answer becomes: everything. If someone is willing to pay, and someone is willing to sell, who are we to say no?

But this default answer is itself a moral position — one that exalts consent and willingness-to-pay above all other values. And it is a position that most people, on reflection, do not actually hold. Most of us do not believe that votes should be for sale. That access to justice should be entirely contingent on wealth. That a child's love of learning should be replaced by a price signal. The question is whether we are willing to say so — publicly, together, and with enough moral seriousness to resist the drift.


Key Takeaways

  • A market economy is a tool. A market society is a way of life in which market values dominate every domain — including those where they do not belong.
  • When everything is for sale, inequality stops being merely uncomfortable and becomes a direct threat to the equal standing that democracy requires.
  • Markets are not neutral. When they enter domains like education, civic participation, or human care, they can corrupt the meaning of those practices — not just change their price.
  • Democracy requires shared common life — spaces, institutions, and experiences that cross social boundaries. Marketization enables exit from those spaces and slowly destroys them.
  • The only remedy is a public debate — frank, morally serious, and genuinely contested — about what markets should govern and what they should not.

In the end, the question of markets is not mainly an economic question. It is a question about how we want to live together. Are there goods that money cannot buy — not because no one will sell them, but because buying them destroys what made them valuable in the first place? The answer to that question will shape what kind of society we become.

Retirement Goal Setting (Chapter 3)

📘 Chapter 3: Retirement Goal Setting

Book: Retire Rich; Invest Rs 40 a day – P V Subramanyam, 2010

✍️ "Without goals, and plans to reach them, you are like a ship that has set sail with no destination." – Fitzhugh Dodson
Retirement planning is exactly that: setting a precise, money-backed destination.

1. SMART goals: The foundation of retirement planning

The chapter insists that any retirement goal must follow the SMART principle. Below is how each element applies to your retirement journey:

Letter Meaning Application to retirement (from chapter)
S Specific "I want to retire when my portfolio is worth ₹2 crores" (not just 'retire early'). Or retire at age 55 with defined corpus.
M Measurable Quantify in rupees: monthly investment, target corpus, expenses. Example: Rahul’s goals were rewritten in exact monthly amounts.
A Achievable Can you really invest ₹40,000/month? If not, adjust expenses, delay retirement or downsize other wishes.
R Realistic Based on income, inflation, life expectancy. Don’t assume unrealistic returns. Be honest with yourself.
T Tracked Use portfolio tracker or simple Excel sheet. Like checking train stations to ensure you're on right track.

Why it matters: vague dreams stay dreams. Written, trackable goals become tangible financial targets.

2. Real-life transformation: Mr. Rahul Agarwal’s journey

The chapter narrates a powerful case: Rahul, age 43, monthly investing ability ₹33,000. Initially he was saving for his daughter’s education (₹18k/month), a foreign tour (₹12k/month), and only ₹3k for retirement. But when the true retirement need was calculated, he needed to invest ₹40,000/month for 15 years — an emotional shock (denial, then anger). After re-evaluating, he reprioritized ruthlessly: retirement became top priority.

📊 Goal reprioritization: before vs after

Figure 1: Monthly allocation shift – Rahul moved retirement from ₹3k to ₹24k, funded by reducing daughter's goal and postponing foreign trip to bonuses only. This made the retirement goal achievable.

Key insight from Rahul's case: Retirement cannot be downsized or avoided. If you delay saving, the required monthly investment grows dramatically. Prioritization is hard, but numbers never lie.

  • Initial ranking: Daughter > Foreign trip > Retirement
  • Revised ranking: Retirement > Daughter's needs > Foreign trip (only if annual bonus permits)
  • Result: Clearer financial peace, no Singapore trip guilt, and a solid retirement plan.

3. Why retirement is non-negotiable

The author highlights a harsh truth: "Retirement cannot be downsized, postponed or avoided! Even if one spouse dies, the other still needs financial security." That makes retirement the most important incentive to save. Many people put children's goals or luxuries first, but neglecting retirement leads to dependency in old age.

💡 Practical rule: Before saving for vacation, car or lavish wedding, first secure your retirement kitty. You can borrow for education but not for old age survival.

4. Understanding retirement expenses – major categories

Chapter 3 includes a detailed retirement expense calculator. Tracking your likely expenses (with inflation) is the only way to know your target. Based on the categories listed (Home, Utilities, Food, Health, Transport, etc.), we can visualise a typical retiree's monthly expense pie.

🥧 Typical retirement monthly expenses (illustrative breakdown)

Figure 2: Common expense buckets derived from the "Retirement expenses calculator" in the chapter. Housing, healthcare and food often dominate. Inflation increases these amounts every year.

In the book, the worksheet includes entries for mortgage, electricity, groceries, medical insurance, car maintenance, and even pet care. The message: list every single outflow. Without this, you cannot compute the required retirement corpus.

5. Making your goal ACHIEVABLE & REALISTIC

After setting a specific number, you might realize your monthly savings are insufficient. The chapter gives four practical levers to pull:

  • Reduce current expenses (cut lifestyle inflation, eating out, unnecessary subscriptions).
  • Invest more – redirect money from less critical goals.
  • Downsize other goals (like wedding, house renovation, luxury travel).
  • Retire later (extend working years by 2–3 years if health allows).

Rahul’s revised plan used exactly these steps: instead of ₹40k shortfall, he cut his daughter’s education allocation in half and used bonus for foreign trip. That made retirement realistic.

6. The power of consistency: growth of ₹40,000 monthly over 15 years

To appreciate why Rahul needed ₹40k/month, the chapter implies the power of compounding. Though returns vary, a disciplined saver can build a sizeable corpus. The line chart below shows a hypothetical growth at 8% annual return – illustrating how steady investing builds wealth over time.

📈 Compounding in action: monthly ₹40,000 over 15 years

Figure 3: Hypothetical corpus growth (₹ in lakhs) – assuming ₹40,000 invested each month, 8% annual return, compounded monthly. Actual returns vary, but regular investing creates momentum.

The chart shows that contributions alone would be ~₹72 lakhs (180 months × 40k), but with compounding the final amount could be around ₹1.39 crore, providing a strong retirement base. This explains why the author insists on hitting the required monthly investment rather than skipping months.

7. Track your goals – the last "T" in SMART

The train analogy is simple: when travelling by train, you check stations to know you're on course. Similarly, track your retirement portfolio at least once a quarter. Use a portfolio tracker or a plain excel sheet. The author advises writing down your goal explicitly: "unwritten goals are just dreams, written goals suddenly seem tangible."

  • Set the goal (specific corpus & timeline).
  • Ensure it is SMART (use the table above).
  • Write it down on paper/digital tracker.
  • Start investing systematically (SIPs, PPF, equity, etc.).
  • Keep track – rebalance and review annually.

8. Caveats: Beware of bull market traps

⚠️ Important warning from chapter: A strong bull run may tempt you to reduce your monthly retirement savings. For example, if your portfolio jumps 45% in two years, you might think "I can invest less now because returns will make up the shortfall." This is dangerous – markets are unpredictable. Stick to your planned monthly investment. Over-optimism can derail a decade of hard work.

Never assume that a temporary rally will continue. True retirement readiness comes from consistent saving, not timing the market.

9. Actionable steps – Your retirement blueprint

Based on the entire chapter, here’s a clear summary checklist:

  1. Calculate realistic retirement expenses (use an expense worksheet like the one in the book). Factor inflation (usually 6–7%).
  2. Define your target retirement corpus (e.g., ₹2 crore, ₹3 crore depending on lifestyle).
  3. Use a retirement goal calculator (like the one given here) to find required monthly savings.
  4. Compare with current monthly investing ability – if short, reprioritize other goals (education, vacation, gadget, home upgrades).
  5. Rank retirement as #1 goal – treat it as a fixed mandatory expense.
  6. Invest that amount every month without fail. Use a mix of equity (for growth) and debt (for stability).
  7. Every year, track your progress: update portfolio value, check if you are on track to meet the target. Adjust if required (increase investment with salary hikes).

10. Final takeaway from chapter 3

Retirement goal setting is not about age alone – it's about money and prioritisation. The story of Rahul shows that honest number-crunching may trigger emotional resistance, but reprioritising brings freedom. Retirement can't be downsized, so treat it as the non-negotiable pillar of your financial life. Start early, be SMART, and track regularly. As the author says: "Numbers don't lie."

Planning for Retirement (Chapter 2)


See Other Book Summaries on Investment    Download Book    Download Chapter    Book Index    « Previously    Next »   

📘 Planning for Retirement: Not Planning is Dangerous!

Key message from the chapter: "Failing to plan, is planning to fail." Retirement planning isn't just about hobbies or where to settle — it’s about financial independence, managing money wisely, and building a safety net for your older years. This report explains the core findings from Chapter 2 in simple, everyday language, with numbers and visuals to help you see why acting today matters.

🔍 What is retirement planning? (The money side)

Most people think retirement means free time or moving to a peaceful town. But financially, retirement planning means:

  • - Deciding when to start investing exclusively for retirement
  • - Choosing at what age you want to stop full-time work
  • - Managing life insurance, medical insurance, and critical care needs
  • - Creating your own "pay cheque" when you no longer have a salary

Without a plan, even a high earner can run out of money. The chapter warns: ignoring retirement is like planning to struggle in your sixties and beyond.

⚠️ Why you need to plan for retirement (11 solid reasons)

The author lists several practical reasons. Here are the most important ones:

Reason Why it matters
1. Protect against financial risks Early death, illness, or accidents can destroy income. A plan builds a safety net.
2. Reduce / eliminate debt High-interest debt (like credit card at 51% p.a.) kills your ability to save.
3. Ensure lifestyle if you live long Life expectancy is rising – you may need 30+ years of retirement income.
4. Support career switches or big expenses Children’s education, weddings, or even starting a new passion career needs backup funds.
5. Cost of raising kids A professional degree or foreign MBA can cost upwards of ₹1 crore today.
6. Unforeseen risks Unexpected loss of money or income – retirement buffer helps you stay afloat.
7. Afford assets (house, car, luxuries) We call them assets – they require planning even after retirement.
8. Retire on your own terms You don’t want to depend on children for money – retirement corpus gives dignity.
9. Pay for un-insurable medical expenses Old-age nursing, maid, or assisted living costs money. Insurance has limits.
10. Leave wealth for children/grandchildren If you wish to pass on assets, include that in the plan.
11. Deal with life’s unexpected surprises Funny situations (or hard times) need financial preparedness.

👩 Women & retirement – why planning is even more critical

The chapter highlights that women in India often earn less, take career breaks (child rearing, family care), and live longer than men. On average, a woman may need retirement income for 5-8 more years than her male partner. Many married women do not actively manage family finances, leaving them vulnerable if widowed or divorced.

✔ Take charge! Women should understand risk & return, inflation, long-term care costs, and learn about demat accounts, mutual funds, and unit-linked plans. Managing a house means you already make daily money decisions — you can master retirement finance too.

🧭 Step-by-step plan: From confusion to clarity

The book simplifies retirement planning into small, manageable steps. Below are the building blocks:

  • Step 1: Estimate retirement expenses — both daily needs (food, shelter, clothes) and large costs (house, car, travel).
  • Step 2: Separate non-negotiable expenses (nursing, medical insurance, inflation impact) from discretionary expenses (eating out, entertainment).
  • Step 3: List all your assets (home, gold, shares) and liabilities (loans). Calculate net worth = Assets – Liabilities.
  • Step 4: Compare retirement income vs expenses. Only safe if income is much higher than expenses, because inflation will eat the gap.

Also, don't forget to make a Will so your assets go where you wish. And always check insurance coverage after adjusting for 20 years of inflation!

📋 What to track: Assets, Liabilities & Cash flows

Assets (what you own) Liabilities (what you owe)
Home, property, gold, equity shares, provident fund, life insurance cash value Home loan, car loan, personal loan, credit card debt
✅ Ask: Is there a nominee? Any tax liability? How liquid is the asset? Is it insured?

For cash flows: identify certain inflows (pension, annuity, RBI bonds), reasonably certain (dividends from blue chips), and uncertain inflows. This helps you build realistic retirement income.

📊 The three income vs expense scenarios

When you compare your retirement income and expenses, only one situation is safe:

  • ❌ Expenses = Income (dangerous, any shock breaks the balance)
  • ❌ Expenses > Income (disaster)
  • ✅ Expenses < Income — but only if income is far higher than expenses, because inflation will push you into the danger zone over time.
*Hypothetical monthly values (₹ thousands) illustrating how expenses can easily equal or exceed income without proper planning. The goal: keep income well above expenses.

🍛 Eye-opening calculation: Your food bill alone (no inflation!)

The author gives a simple but powerful example: If each meal costs ₹75 on average, and you eat 3 meals a day, your daily food cost = ₹225 per person. For a retired life of 25 years (age 65 to 90), total food cost per person = ₹20,25,000. For a couple = ₹40.5 lakhs. And this ignores inflation, medical costs, housing, or entertainment!

25-year basic food cost (no inflation). The real number will be much higher due to rising prices.
Retirement can be split into 4 blocks (10 years each). Each phase has different needs and energy levels.

🏠 Housing & hidden monthly expenses: Where money leaks

After food, housing is the second biggest cost. A big house costs much more to maintain (maid, gardener, electricity, taxes, society charges). If children have moved out, downsizing can dramatically lower your outflow. Also check recurring "monthlies":

  • - Two landlines? multiple mobiles?
  • - Unused magazine subscriptions or gym memberships paid by former employer
  • - Spare car or extra household help

Small but recurring expenses often hurt the most. The trick: use credit cards like a charge card (pay full each month) – interest on credit is a strict NO for retirees.

📈 The silent killer: Inflation even on basic food

If inflation runs at 6% per year, the couple's annual food expense (today ₹1,64,250) grows year after year. The line chart below shows how the same meals become heavier on the pocket over 25 years.

Annual food cost for a couple (₹) with 6% inflation. Without planning, even basic expenses skyrocket.

⚠️ Beware of generic rules: "70% of pre-retirement expenses"

Many advisors suggest you need 70% of your current income post-retirement. The author says: take this with a pinch of salt. Everyone’s lifestyle, medical needs, and location differ. Instead, do a detailed, personalised estimate. Don’t forget big-ticket items: buying a house, cars, white goods, travel, and uninsured medical bills.

✅ Action checklist – Start today, even if you are in your 20s

What to do Why it matters
Start early & maintain a financial plan Compound interest works magic – small savings grow huge over decades.
Build an emergency + retirement fund separately So you don’t dip into retirement corpus for urgent needs.
Review insurance coverage every 5 years Inflation erodes cover; increase sum assured accordingly.
Estimate realistic retirement expenses (non-negotiable first) Prevents nasty surprises when income stops.
Women: take active role in family investments Because women live longer and often outlive spouses.
Downsize home if children have left Reduces monthly maintenance, taxes, utilities.
Create a will & nominate for all assets Ensures your money goes where you intend.
💡 Final thought from Chapter 2: Retirement planning isn’t scary. Break it into small steps, list your assets and expenses, and remember that “failing to plan is planning to fail.” The best time to start was yesterday; the next best time is today.

How does Google Gemini Client accesses the API Key?

See All on GenAI    « Previously

Gemini said

When you instantiate genai.Client() without passing any arguments, the Google GenAI SDK automatically looks for your API key in your system's environment variables.

Specifically, it checks for these two variables:

  1. GEMINI_API_KEY (Recommended)

  2. GOOGLE_API_KEY (Supported as a fallback or for legacy compatibility)

If it finds either of these variables, it automatically injects the key into the client. If both happen to be set, GOOGLE_API_KEY takes precedence.

Why do it this way?

This is a standard security best practice. By relying on environment variables rather than explicitly passing the key like genai.Client(api_key="YOUR_KEY"), you avoid hardcoding sensitive credentials directly into your source code, preventing accidental leaks if you push your code to a public repository like GitHub.

How to set the environment variable

To make this code work on your machine, you need to set the variable before running your script.

On Mac/Linux (Terminal):

Bash
export GEMINI_API_KEY="your_api_key_here"
python your_script.py

On Windows (Command Prompt):

DOS
set GEMINI_API_KEY=your_api_key_here
python your_script.py

Alternatively, in Python (using python-dotenv): If you are using a .env file to manage your secrets, you can load it before calling the client:

Python
import os
from dotenv import load_dotenv
from google import genai

# This loads the GEMINI_API_KEY from your .env file into the environment
load_dotenv() 

client = genai.Client()
response = client.models.generate_content(
    model="gemini-3.5-flash",
    contents="Explain how AI works in a few words"
)
print(response.text)
