I often feel that death is not the enemy of life, but its friend, for it is the knowledge that our years are limited which makes them so precious. It is the truth that time is but lent to us which makes us, at our best, look upon our years as a trust handed into our temporary keeping. We are like children privileged to spend a day in a great park, a park filled with many gardens and playgrounds and azure-tinted lakes with white boats sailing upon the tranquil waves.

True, the day allotted to each one of us is not the same in length, in light, in beauty. Some children of earth are privileged to spend a long and sunlit day in the garden of the earth. For others the day is shorter, cloudier, and dusk descends more quickly as in a winter’s tale. But whether our life is a long summery day or a shorter wintry afternoon, we know that inevitably there are storms and squalls which overcast even the bluest heaven and there are sunlit rays which pierce the darkest autumn sky. The day that we are privileged to spend in the great park of life is not the same for all human beings, but there is enough beauty and joy and gaiety in the hours if we will but treasure them. 

Then for each one of us the moment comes when the great nurse, death, takes man, the child, by the hand and quietly says, “It is time to go home. Night is coming. It is your bedtime, child of earth. Come; you’re tired. Lie down at last in the quiet nursery of nature and sleep. Sleep well. The day is gone. Stars shine in the canopy of eternity.”

What Should I Do With ₹60,000 Sitting Idle in My Account?


Lessons in Investing    <<< Previously

This is not a textbook article. It is a real conversation — one Indian household investor trying to make one smart decision with ₹60,000 — while navigating a home loan, an equity portfolio, a 10-year-old PPF, and a US-Iran war rattling global markets.

Most personal finance advice floats at a comfortable altitude of generality. "Invest in diversified assets." "Build an emergency fund." "Avoid emotional decisions." All true, all useless without context. This blog post is different. It traces a real financial decision from confusion to clarity, one question at a time. The investor in this story had ₹60,000 sitting in a current account, knew they spent irrationally when money was visible and accessible, and wanted to know what to do. What followed was a surprisingly rich financial education.

First, the Full Picture

Before any advice can be useful, you need to lay out the complete financial snapshot honestly. Here is what the investor's situation looked like at the start of this conversation:

Financial Snapshot

Asset / Liability Value
Home Loan (below 8% interest) ₹39,00,000
Equity Investment — Nifty50 & Sensex ₹15,00,000
PPF Account (10+ years old) ₹60,000
Current Account (idle, temptation risk) ₹60,000
Emergency Fund None

This is actually a reasonably solid financial base. A below-8% home loan is well within manageable territory. ₹15 lakhs in Nifty50 shows a long-term investing mindset. PPF is a quiet compounder. The only structural gap — and it is a significant one — is the complete absence of an emergency fund. Without one, every unexpected expense becomes a crisis, and the first thing people raid in a crisis is their equity portfolio, usually at the worst possible time.

The Psychology Problem Is the Real Problem

The investor stated something important and self-aware: they tend to spend irrationally when money sits in their current account. This is not a character flaw — it is human psychology. Behavioural economists call it the "money availability effect." When money is visible and accessible, our mental accounting treats it as "available for spending" regardless of whether it was meant for savings. The solution is architectural, not motivational. You do not fight temptation with willpower; you remove the temptation from sight.

"The goal is not to resist spending the ₹60,000. The goal is to make spending it slightly inconvenient enough that impulse cannot win." The core insight of this conversation

This is precisely why liquid mutual funds — not prepayments, not more equity investments, not PPF top-ups — are the right instrument for this specific problem. A liquid fund takes money out of your current account, puts it somewhere that still earns a return, but introduces a one-day withdrawal lag that defeats impulse buying while preserving genuine emergency access.

Why Not Prepay the Home Loan?

This is often the first instinct when someone has a lump sum sitting idle. Debt feels bad. Paying it down feels virtuous. But the math here does not support it — at least not yet. The home loan is below 8%, which means the cost of this debt is lower than what the investor's own Nifty50 portfolio is historically earning (roughly 11–13% CAGR over long periods). Paying off a 7.9% loan to free up capital that was already earning 12% is not a win. More critically, prepaying a lump sum loan converts your cash into an illiquid asset. If an emergency hits the following month and you have no accessible fund, you would have to borrow again at a higher rate. Prepayment is a good decision later — not as the first move when you have zero emergency cushion.

Build Emergency Fund in a Liquid Mutual Fund

Here's why it fits perfectly in this situation:

  • Liquid mutual funds (like HDFC Liquid, SBI Liquid, etc.) give ~6.5–7% returns, better than a savings account
  • Your money is redeemable within 1 business day — true emergency access
  • It's out of your current account, so it removes the psychological temptation to spend it
  • It builds the habit of saving systematically
  • Once you reach 3–6 months of expenses (say ₹2–4 lakhs depending on your lifestyle), you graduate this money into equity investments

The ICICI Prudential Liquid Fund — Decoded

The recommendation that emerged from this conversation was the ICICI Prudential Liquid Fund — Direct Growth Plan. But recommending a fund name is not enough. Understanding what it actually does with your money is what builds genuine confidence. Here is the plain-English version.

Where Does Your Money Go?

When you invest ₹60,000 in this fund, it does not sit in one place. Roughly 38.73% is deployed into Commercial Papers — short-term IOUs issued by companies like NABARD, HDFC Securities, Bajaj Finance, and Kotak Securities. About 35.58% goes into Certificates of Deposit — essentially short-term deposits at top Indian banks including Axis Bank, HDFC Bank, Punjab National Bank, and State Bank of India. Another 18% sits in TREPS (Tri-Party Repo), which is essentially overnight lending to financial institutions against government security collateral — the closest thing to cash in the mutual fund world. The remaining small portion includes direct Government of India securities.

There are no stocks here. No real estate. No derivatives or complex structured products. This is a fund that lends money to India's most creditworthy borrowers for 7 to 90 days, collects interest, and repeats. The portfolio refreshes itself roughly every 50 days.

The Credit Quality Story

Over 71% of the portfolio holds instruments rated CRISIL A1+ — the absolute highest short-term credit rating available in India. Another ~7% carries equivalent top ratings from ICRA and Fitch. The Sovereign portion (Government of India) adds another 1.58% of zero-default-risk assets. In total, nearly 80% of the portfolio is in the safest possible short-term instruments. This is about as close to a government guarantee as a non-government fund can get.

The Numbers That Matter

Fund Performance & Risk Metrics

Metric Value
1-Year Return (CAGR) 6.31%
3-Year Return (CAGR) 6.29%
5-Year Return (CAGR) 6.91%
Yield to Maturity (YTM) 6.49%
Expense Ratio (Direct Plan) 0.20%
Modified Duration 0.11 (extremely low rate sensitivity)
Sharpe Ratio 7.86 (outstanding risk-adjusted return)
Annualised Std. Deviation 0.20% (near-flat NAV growth)
AUM (Feb 2026) ₹53,738 crore
Average Maturity ~50 days

The Sharpe Ratio of 7.86 is the standout number here. It measures how much return you earn per unit of risk. A Sharpe Ratio above 1 is generally considered good. At 7.86, this fund is delivering exceptional risk-adjusted returns — which simply means you are being very well compensated for the (already negligible) risk you are taking. The Standard Deviation of 0.20% means the NAV barely fluctuates — it grows in an almost perfectly straight line. That is exactly what you want from a fund whose job is to park your emergency money safely.

Direct Plan vs Regular Plan

Choosing between Direct Plan and Regular Plan

Always choose the Direct Plan. The expense ratio on the Direct Plan is just 0.20%, versus 0.31% on the Regular Plan. That difference compounds over time.

The Tax Reality — What You Actually Take Home

Here is a piece of financial reality that often gets glossed over. Since April 1, 2023, debt mutual funds — including liquid funds — lost their long-term capital gains tax benefit. Now, regardless of how long you hold, all gains are added to your taxable income and taxed at your slab rate. This means the headline 6.31% return is not what you keep. If you are in the 30% tax bracket, your post-tax return is closer to 4.47%. That sounds disappointing until you compare it honestly to the alternatives: a savings account earns ~3% (also taxable), a current account earns 0%, and breaking a Fixed Deposit early often carries penalties. The liquid fund still wins on post-tax, post-penalty, post-flexibility terms for an emergency fund use case.

The tax math for ₹60,000 parked for one year:

At a 6.31% gross return, you earn roughly ₹3,786 in gains. Even at the 30% tax bracket with 4% cess, you pay about ₹1,181 in tax and net ₹2,605. That is ₹2,605 more than your current account pays. More importantly, your ₹60,000 is no longer sitting in front of you, waiting to be spent impulsively.


For your specific use case (emergency fund), the comparison isn't against equity. It's against the alternatives:

Option Post-Tax Return (30% bracket)
Savings Account ~2.5–3% (also taxable)
FD (1 year) ~4.5–5% (also taxable at slab)
ICICI Prudential Liquid Fund ~4.5–5.1%
Money sitting in Current Account 0%

Liquid funds are roughly on par with FDs post-tax, but with one massive advantage — you can withdraw in 1 business day, whereas breaking an FD often has penalties.

The War Nobody Planned For

One dimension that was not in anyone's financial plan: the US-Iran conflict that escalated sharply in early 2026. The attack on February 28, 2026, which resulted in the death of Iran's Supreme Leader and triggered retaliatory missile strikes across the Middle East, sent shockwaves through global commodity and financial markets. Brent crude surged past $117 per barrel — a nearly 60% rise in weeks. The Indian rupee weakened to a record low against the US dollar. Sensex and Nifty50 fell 14–15% year-to-date, erasing a significant portion of equity gains.

⚠ Geopolitical Context — March 2026

Nifty50 and Midcap indices corrected 9% since the onset of the conflict. FII outflows exceeded ₹60,000 crore in the March series alone. A ₹15 lakh equity portfolio is estimated to be worth approximately ₹12.75–13 lakh at current levels. These are paper losses, not permanent — but they are real for now.

The correct response to paper losses in a diversified Nifty50 investment is to hold, not sell. Historical recovery patterns post-conflict (including Russia-Ukraine in 2022) confirm that patient investors are rewarded.

Importantly, this geopolitical crisis does not change the liquid fund recommendation — it actually strengthens it. Liquid funds invest only in short-term debt with an average maturity of 50 days. They hold no equities and no oil-linked assets. The fund's modified duration of 0.11 means even a significant RBI interest rate hike — which might come if oil-driven inflation persists — would move the NAV by barely 0.11%. In a period of equity volatility and global uncertainty, the liquid fund is genuinely the safest harbour for short-term money.

The Hidden Gem: The 10-Year-Old PPF

One piece of information revealed late in the conversation changed the analysis meaningfully: the PPF account is over 10 years old. This matters because PPF partial withdrawal rules allow up to 50% of the balance from the 4th preceding year to be withdrawn after the 7th year — completely tax-free. But more importantly, a 10-year-old PPF account with a balance growing at 7.1% per annum tax-free is, on a post-tax equivalent basis, delivering roughly 10.2% for someone in the 30% bracket. That beats nearly every other safe instrument available in India today — including the liquid fund.

The revised recommendation therefore became: leave the PPF completely untouched and let it compound to maturity. It is the highest post-tax returning safe asset in this investor's portfolio, immune to stock market crashes, oil price shocks, currency depreciation, and war. The ₹60,000 in the current account should go into the liquid fund to serve as the emergency fund. These two instruments — PPF for long-term compounding, liquid fund for emergency access — work as a complementary pair rather than competing options.

The Final Playbook

After all the analysis, the recommendations distil to four clear actions — each with a specific reason behind it:

Action Plan

Asset Action Why
₹60k Current Account Move to ICICI Prudential Liquid Fund — Direct Growth today Removes temptation, builds emergency fund, earns 6%+
PPF (10+ yrs old) Do not touch — let it compound to maturity 7.1% tax-free = ~10.2% pre-tax equivalent, safest compounder
₹15L Nifty50/Sensex Hold through war volatility, do not panic sell Paper loss, not permanent; recovery historically follows conflict
₹39L Home Loan No change, no prepayment yet Sub-8% rate is cheaper than equity returns; emergency fund comes first

The Bigger Lesson

The most important insight from this entire conversation is not about liquid funds or tax slabs or credit ratings. It is about the relationship between self-knowledge and financial planning. This investor knew something crucial about themselves — that visible money triggers irrational spending. That single piece of self-awareness unlocked the entire strategy. The right financial instrument is not always the highest-returning one. It is the one that works for you, with your psychology, in your specific life context.

An emergency fund is not exciting. A liquid fund earning 6% is not a story you tell at dinner parties. But it is the foundation upon which everything else — the equity portfolio, the PPF, the home loan management — can function without crisis. Getting the foundation right is, in the end, the most sophisticated financial move you can make.

"You have a solid investment base, a manageable loan, and enough self-awareness to know your spending habits. The missing piece was the safety net. Once that is in place, your financial foundation will be genuinely strong." The conclusion that matters

Artificial Intelligence · The Decade Ahead

We're 10% Into the AI Revolution — And It's Already Rewriting Everything

On recursive self-improvement, the 92-gigawatt problem, and why the slope is about to go vertical

Let me be direct: we are in the middle of the most consequential technological transition in human history, and most people — including most policymakers — haven't begun to feel it yet. We're perhaps 10 or 15 percent into the real impacts of artificial intelligence. You can see it. You can feel it at the edges. But the core disruption? It hasn't arrived. What's coming is something far larger, far faster, and far more disorienting than the chatbot era has suggested.

The Year of Agents Is Already Here

There's something I call the San Francisco consensus — a shared belief among nearly everyone building frontier AI right now that 2025 is the year of agents. Not chatbots. Not autocomplete. Agents: AI systems that reason, plan, take multi-step actions, and operate autonomously over extended periods. The scaling of agent deployments and reasoning capabilities is happening at an enormous and accelerating rate.

To understand what that means practically, consider what's already changed in software development. A year ago, the ratio was roughly 80% human-written code, 20% AI-generated. Today, for the best teams I know in the Bay Area, it has completely flipped: 20% human, 80% AI. What drove that flip wasn't just better tooling. The underlying large language models became deeper thinkers — capable of longer, more coherent chains of reasoning, producing higher-quality outputs across more complex tasks.

"The best analysis I can come up with is it's not the Claude Code part. It's that the underlying LLM can produce more reasoning over time, better quality tokens over time. It's a deeper thinker."

On the shift in software development

I've been programming since high school. I moved to the Bay Area at 21 and built my career in software. Watching what these systems can do now, I have a clear-eyed view: there is not a programming task I could perform that a current top-tier model cannot match or exceed. When I watched one of these systems rewrite a C compiler in Rust, I thought: declare victory. The era of the individual programmer as the primary unit of software creation is effectively over.

Recursive Self-Improvement: The Clock Is Ticking

The thing people in this space talk about — but that most outside of it don't yet fully grasp — is recursive self-improvement. This is the scenario where an AI system begins improving itself: learning faster than humans can supervise, iterating on its own architecture and reasoning, compounding gains in ways that are not linear but exponential.

We don't have true recursive self-improvement yet. The tests exist in labs, they work in constrained demo conditions, but the general capability — "start now, learn everything, discover new things, and report what you found" — does not yet function reliably. The scientists working on this do not agree on the exact approach. But the evidence that it will work is accumulating.

"In this thinking, once you have recursive self-improvement, where the system can begin to improve itself, you have intelligence learning on its own. And in this argument, it will learn faster than we can because we're biologically limited."

On the superintelligence inflection point

The mechanism is worth spelling out clearly. Imagine a tech company with a thousand brilliant AI researchers. Now imagine switching on AI research agents to work alongside them. The constraint on human researchers is biology: sleep, housing, salaries, visas, interpersonal friction, burnout. The constraint on AI agents is electricity. So the question becomes: how many AI research agents could you run? Perhaps a million. And if your evaluation framework clearly measures progress — which in AI it does — then a million agents iterating on model improvement creates a slope that goes nearly vertical. That is the superintelligence moment. The belief in San Francisco is that this arrives within two to three years.

2–3 years: the window within which most frontier AI researchers believe recursive self-improvement — and with it, a superintelligence inflection — becomes possible.

The 92-Gigawatt Problem Nobody Is Talking About Enough

Every major AI lab is out of hardware. Every major AI lab is out of electricity. This is not hyperbole — it is the binding constraint on the entire industry right now. The boom I'm watching is unlike anything I've seen across three or four technology cycles in my career. The numbers involved are staggering: the United States alone will need roughly 92 additional gigawatts of energy to power the AI infrastructure being planned and built.

To put that in context: a large nuclear power plant produces about one gigawatt. We're talking about the equivalent of 92 new nuclear plants worth of electricity demand — added on top of existing consumption — driven primarily by data center construction for AI training and inference.

"Everybody's out of hardware. Everyone's out of electricity. It's a real boom. It's like the biggest boom I've seen. And I've been through three or four of these in my career."

On the infrastructure surge

The good news is that energy permitting reform is happening in the United States, and the rate at which data centers are being approved and built is now accelerating. The grid challenges are being worked through. But this is the chokepoint — not the algorithms, not the chips, not the talent. The race to superintelligence may ultimately be decided by who can build generation capacity fastest.

The Geopolitical Dimension: China, Open Source, and the Edge Computing Bet

China is not behind. This is something I want to say clearly and without the political fog that tends to cloud this conversation. China has enormous capital, exceptional engineering talent, and a work ethic that is at minimum equal to anything we produce in the United States. In robotics hardware, they may already be winning — and I have no desire to lose the robotics revolution the way we lost the electric vehicle race at the consumer end.

What's interesting is China's strategic divergence. Their approach — exemplified by DeepSeek, Qwen, Kimi, and others — is predominantly open source. They've made remarkable progress despite chip export restrictions, which is itself a demonstration of their engineering sophistication. But perhaps more importantly, China is betting on edge computing: embedding AI into the physical environment of Chinese users at massive scale, pervasively and locally.

The United States strategy is centered on AGI and ASI — building toward artificial general and superintelligence in large, centralized compute clusters. China's strategy is different: it's less about central supremacy and more about total environmental saturation with AI at the edge. These are diverging architectures for diverging visions of what AI is fundamentally for.

My estimate is that the world can sustain roughly ten frontier AI labs at scale — the majority in the United States, a few in China, possibly one or two in Europe depending on energy costs, and perhaps one in India. Russia is effectively out of this race for now. The question of whether these labs converge on similar capabilities or diverge toward specialized strengths is one that will define the geopolitical landscape of the next decade.

What Happens to Work — and Who Wins

The labor market implications are already becoming visible, and they don't map onto the simple narratives. It is not the case that all jobs disappear or that everything remains the same. The pattern I see emerging is bimodal: a relatively small number of very large companies, and a very large number of very small companies. The middle layer — medium-sized firms dependent on large teams of knowledge workers — gets compressed.

Within software specifically, what I observe is that the very top programmers — the ones with exceptional mathematical reasoning skills — become more valuable, not less. These are the people who can direct, evaluate, and constrain AI systems. They understand parallelization. They can write specifications, build evaluation functions, and run overnight agent loops that produce in eight hours what used to take weeks. They become directors of a programming system rather than individual contributors within one.

"It's always been true, speaking as your local arrogant programmer, that the very top programmers were worth ten times more than the ones right below. Those people will become more valuable, not less valuable, because these systems need to be controlled by humans at the moment."

On the future of technical talent

For physical labor, the story is more complex. Highly skilled mechanical work — aerospace, precision manufacturing, anything requiring in-situ human judgment about novel physical situations — remains difficult to automate in the near term. Low-skilled physical labor, by contrast, is highly exposed. But the general principle holds: the learning loop that accelerates fastest wins, whether that's a company, a country, or an individual.

Safety, Chernobyl, and the Wake-Up Call We Haven't Had

I want to be precise about something I've said before, because it is often misread. I am not endorsing a catastrophic AI event. I am describing — as a matter of prediction, not preference — that the world may require a modest, Chernobyl-scale incident before governments take AI risk seriously enough to act collectively.

Today, the share of congressional attention devoted to AI policy is well under one percent. Governments are busy; they are driven by near-term political pressures; they move slowly on abstract systemic risks. The real dangers are not science fiction. They include biological attacks enabled by AI, destabilization of democratic processes, and the exploitation of children and minors through AI-generated content — the last of which I consider an uncrossable line that we have so far failed to adequately address.

"It may take such a tragedy, hopefully a small one, to awaken the world to understand that these things are real... We're in brutal competition, we hate each other... but we are all in it together, right, over this issue."

On global AI governance

My deeper frustration is structural. We have over-relied on technologists to solve what are fundamentally political, ethical, and governance problems. The people who need to be centrally involved — historians, governance scholars, human psychologists, political philosophers — are largely absent from the rooms where AI policy is being shaped. That has to change.

Steering Toward Abundance: What Must Be Done

If we reach ASI — artificial superintelligence — within this decade, as I believe is probable, the single most important question is what values it embeds. Not its capabilities. Its values. A superintelligent system oriented toward human flourishing, freedom of expression, and democratic self-determination looks entirely different from one optimized for control or extraction. This is not a technical problem. It is a civilizational one.

The United States has a genuine comparative advantage here, but it is not guaranteed. The values that make American innovation possible — pluralism, individual freedom, the right to speak and associate — are also the values that need to be encoded into the systems we build. Winning the AI race matters, but winning it while losing what makes America worth winning for would be a catastrophic form of success.

On immigration, the argument is simple: the smartest people in the world should want to build here, and we should want them here. High-skilled immigration is not a social program; it is a national security and technology strategy. Every brilliant researcher who builds the next frontier model in the United States rather than elsewhere is a direct contribution to the kind of AI future I want to see.

The abundance thesis is correct. AI can and should generate extraordinary human flourishing — collapsing the cost of expertise, expanding access to education and healthcare, enabling scientific discovery at scales previously impossible. None of that is inevitable. It requires deliberate choices, made now, by people with the courage to think on the timescale the moment demands.

Conclusion

  • We are roughly 10–15% into the real impacts of AI. The disruption visible today is a preview, not the main event.
  • The year of agents is here. AI systems that reason, plan, and act autonomously are already flipping the 80/20 human-to-AI ratio in software development.
  • Recursive self-improvement — the true superintelligence trigger — does not yet exist in deployable form, but lab evidence is accumulating. The likely window: two to three years.
  • The binding constraint is energy, not algorithms. 92 additional gigawatts of electricity demand are coming; whoever builds generation capacity fastest shapes the race.
  • China is a peer competitor, not a laggard. Their open-source, edge-computing strategy is coherent and sophisticated, and they are winning in robotics hardware.
  • Labor bifurcates: top technical talent becomes more valuable; mid-tier knowledge work is most exposed; high-skill physical labor is more durable than low-skill physical labor.
  • A governance wake-up call — hopefully small — may be necessary before the world takes AI safety seriously enough to act across geopolitical divides.
  • The critical missing voices in AI policy are not technologists but ethicists, historians, political scientists, and governance experts.
  • Winning the AI race matters only if we encode the right values — freedom, pluralism, human alignment — into the systems we build. The how of winning is as important as the winning itself.
