One of my biggest realisations in China: reverse migration is real. Met an old friend in Shanghai-Ivy League, ex-FAANG-who just moved back with his family. Beyond the high-tech jobs, his real reasons were cleaner air, world class infrastructure, and top education for his kids. If India cracks these 3, we’ll see far more Indians coming home too and building for India.

[Ihtesham Ali @ihtesham2005]

A Stanford CS professor told his class something at the start of the semester that made half the students close their laptops.

He said the skill that will separate the people who thrive in the next decade from the people who stall has almost nothing to do with coding.

His name is Andrew Ng, and he has trained more machine learning engineers than almost anyone alive.

Here is what he said, and why it changes how you should be learning right now.

He said the bottleneck is no longer writing code. It is knowing which problems are worth solving in the first place. For thirty years, being a good engineer meant being able to build what someone else defined. In the world that is arriving, every engineer has infinite leverage to build almost anything, which means the person who picks the right thing to build now wins by orders of magnitude over the person who builds the wrong thing flawlessly.

His framework for problem selection is deceptively simple. He calls it the three-question filter.

The first question is whether the problem you are working on actually matters to someone who would pay for it or use it daily. Most students fail here. They work on projects that are interesting to them and nobody else, and then wonder why the portfolio produces no offers.

The second question is whether the problem is still hard now that AI exists. If a single prompt to a hosted model solves it, the problem is no longer valuable to solve yourself. The interesting problems live in the gap between what AI can do alone and what it can do when combined with domain knowledge, careful system design, and data nobody else has access to.

The third question is the one most people skip. Can you actually ship a working version in a week. Not a polished version. A crappy, embarrassing, actually-functional version. Ng said the number one predictor of which of his students ended up building something important was not talent. It was the willingness to ship something bad fast and then improve it in public.

He said the students who kept tweaking in private for six months before showing anyone almost always produced worse final work than the students who shipped a broken version on week one and iterated based on real feedback.

The people who are actually winning right now are not the ones with the best ideas.

They are the ones who learned to pick problems that matter and ship solutions that barely work, before anyone else has even finished thinking about it.

Every Empire Dies the Same Way

They miss the next technology.

Most civilizations do not disappear because they are weak.
They disappear because the technology that once made them powerful becomes obsolete.

History is filled with empires that looked permanent—until the rules of power changed. When those rules changed, their decline was often swift and irreversible.

Egypt ruled the ancient world for nearly two thousand years. Long before Greece rose or Rome existed, Egypt possessed the most advanced state in the Mediterranean world. Its bureaucracy, agriculture, and armies were unmatched. During the Bronze Age, bronze weapons and chariots defined military power, and Egypt mastered both.

But bronze had a hidden weakness. It required copper and tin—metals that had to be imported through fragile trade networks.

Then came iron.

Iron weapons were not just stronger; they were dramatically cheaper and far more abundant. But iron required extremely high temperatures to smelt, which meant vast quantities of charcoal. Charcoal meant forests. Forests meant geography.

Egypt was a river civilization surrounded by desert. It simply did not have the forests needed to produce iron at scale. Assyria did. Situated near the wooded hills of Anatolia and the Levant, Assyria mastered iron metallurgy and equipped its armies accordingly.

Within a few centuries Assyria dominated the Near East with iron-equipped forces. Egypt survived, but it never again returned to the center of global power.

A civilization that had ruled for millennia missed the next technological age.

The pattern would repeat across centuries.

In medieval Europe the armored knight was the ultimate weapon of war. A knight was a walking fortress—encased in steel, mounted on a powerful warhorse, and supported by an entire feudal economy. Training one took decades. Equipping one cost enormous wealth. Society itself was organized around sustaining this elite warrior class.

Then came a weapon made largely from wood.

The English longbow could be wielded by commoners. A skilled archer could release ten arrows in the time it took a knight to cross the battlefield. At battles such as Agincourt in 1415, thousands of English archers faced a much larger French army filled with heavily armored nobles.

The result was devastating.

The economics of war had changed. A weapon that cost almost nothing could neutralize a system that required immense wealth to maintain. The knight did not vanish overnight, but its dominance ended.

Technology had quietly rewritten the cost structure of power.

The same dynamic unfolded in South Asia.

For centuries Indian armies relied on war elephants as their ultimate battlefield weapon. Elephants towered over infantry formations, crushed cavalry charges, and carried commanders above the battlefield. They were symbols of royal authority and instruments of shock warfare.

But elephants belonged to an older military age.

In 1526 at the First Battle of Panipat, the Central Asian warlord Babur faced the much larger army of the Delhi Sultan Ibrahim Lodi. Lodi possessed tens of thousands of troops and hundreds of war elephants. Babur’s force was far smaller.

But Babur brought gunpowder artillery.

When the cannons fired, the explosions terrified the elephants. The animals turned and stampeded through their own ranks. Within hours the Delhi Sultanate collapsed and the Mughal Empire was born.

A military system that had dominated the subcontinent for centuries was undone in a single afternoon.

Numbers had not changed. Technology had.

Even more dramatic was the rise of the Mongols.

To the sophisticated civilizations of the thirteenth century, the Mongols appeared primitive. China had cities and advanced engineering. Persia had wealth and scholarship. Europe had castles and armored knights.

The Mongols had horses.

But their system of warfare was revolutionary. Each warrior rode multiple ponies, allowing Mongol armies to travel extraordinary distances without exhausting their mounts. Their composite bows could penetrate armor at long range, and their decentralized command structure allowed rapid maneuver warfare that stunned slower armies.

Mobility became the decisive advantage.

Within a few decades the Mongols built the largest contiguous empire in human history, stretching from Korea to Eastern Europe.

Civilization had been defeated by adaptation.

Modern history offers an even clearer example.

At the beginning of the Second World War the most powerful warships ever built were battleships—massive floating fortresses armed with gigantic guns capable of firing shells across vast distances. Nations poured immense resources into these symbols of naval supremacy.

Then aircraft carriers arrived.

Aircraft launched from carriers could strike ships from hundreds of kilometers away—far beyond the range of battleship guns. In the Pacific War carriers destroyed battleships without ever entering their range.

Within a few years the battleship became obsolete.

Aircraft had replaced armor.

Every military revolution follows the same pattern. A cheaper or more effective technology suddenly destroys the expensive system that once defined power.

Iron replaced bronze.
Longbows humbled knights.
Cannons broke elephant armies.
Aircraft replaced battleships.

Each time the global balance of power shifted.

Today we may be entering another such moment.

For five centuries global dominance belonged to maritime powers that controlled the oceans. The Portuguese began the era of oceanic empires. The Spanish expanded it. The Dutch perfected global trade networks. Britain built a navy so powerful that at one point it exceeded the combined fleets of its rivals.

In the twentieth century the United States inherited this system. Aircraft carriers became the ultimate instruments of global power projection.

Control of the sea meant control of trade. Control of trade meant control of wealth.

But the technologies shaping warfare are changing again.

Drones, artificial intelligence, autonomous systems, and precision missiles are altering the economics of conflict. In modern battlefields inexpensive drones have destroyed tanks worth millions of dollars. A device costing a few hundred dollars can destroy equipment thousands of times more expensive.

When such asymmetries scale, entire military doctrines become unstable.

Even the aircraft carrier—the crown jewel of naval power—faces new vulnerabilities. A single carrier costs more than thirteen billion dollars, yet missiles capable of threatening such ships may cost a tiny fraction of that.

But the deeper shift may not be destruction.

It may be denial.

In the twentieth century dominance meant the ability to project power anywhere in the world. In the twenty-first century victory may simply mean preventing your rival from reaching you.

Access denial can be as powerful as conquest.

Consider the Strait of Hormuz, through which roughly a fifth of the world’s oil supply flows. If even a regional power could credibly deny access to that narrow corridor using missiles, drones, mines, and autonomous systems, the consequences for global trade would be immense.

To challenge a superpower no longer requires conquering its cities. It may only require making key strategic routes too dangerous to enter.

If a navy cannot guarantee safe passage through critical chokepoints, its ability to operate near heavily defended regions becomes far more uncertain.

And that raises an uncomfortable question. If access to a narrow waterway like Hormuz can be contested, what does that imply about operating near Taiwan—surrounded by dense missile networks and advanced defenses?

The balance between offense and defense may be shifting again.

Whenever that happens, the global hierarchy begins to move.

China appears determined not to miss this moment. It is investing heavily in artificial intelligence, robotics, autonomous systems, and advanced manufacturing. It already produces a dominant share of the world’s industrial robots and graduates enormous numbers of engineers every year.

The United States still possesses immense advantages—its universities, capital markets, and technological ecosystem remain powerful. Old powers rarely fade quietly.

But technological transitions are rarely gentle.

Which brings us to India.

Every technological shift divides nations into two groups: those who build the future and those who live inside it.

Egypt missed iron.
Knights missed the longbow.
Elephant armies missed gunpowder.
Battleships missed aircraft.

The twenty-first century will be defined by artificial intelligence, robotics, autonomous warfare, and advanced manufacturing.

The question is simple: who will build it?

India has the population, the talent, and the intellectual capacity to be one of the defining powers of this age. But technological leadership demands long-term focus—investment in science, engineering, industry, and strategic capability.

Yet too often the national conversation revolves around something else entirely.

Instead of debating how to dominate artificial intelligence or robotics, political energy is consumed by the next election cycle and the next round of handouts. Welfare schemes designed to win votes—cash transfers, subsidies, and programs such as “Ladli Behna”—may bring short-term political victories. But they do little to build the scientific, technological, and industrial foundations that determine long-term power.

History offers a harsh lesson: civilizations that focus on distributing wealth before creating it eventually fall behind those that invest relentlessly in capability.

Empires are not lost only on battlefields. Sometimes they are lost in budgets.

A society obsessed with the next election rarely prepares for the next technological revolution.

The countries that dominate the coming century will be those that build laboratories, factories, engineers, and machines—not just welfare rolls.

India therefore faces a choice that will define its future.

It can commit to the hard path of technological leadership—massive investment in research, robotics, AI, manufacturing, and military innovation.

Or it can remain trapped in a narrow cycle of electoral politics and populist giveaways, slowly drifting toward the margins of global power.

Egypt missed iron.
Others missed gunpowder.
Still others missed aircraft.

The question of this century is simple.

Will India seize the age of AI and robotics—or miss it?

Because every empire that misses the next technology eventually learns the same lesson.

It becomes a spectator in a world shaped by others.

Examples are now pouring in about AI-assisted Code Engineering productivity.

The quoted post is a Bhagwad Gita app.

Anthropic has built an entire C compiler with their Claude AI. That is not an easy engineering feat at all.

At this point, it is best for those of us who depend on writing code for a living to start considering alternative livelihoods. I include myself in this. I don't say this in panic, but with calm acceptance and embrace.

As a matter of fact, I did a detailed session with Gemini Pro on how the economy will be shaped by the AI revolution. It was like having an extremely intelligent economic philosopher debating you. I asked it to critique its own work and it did a fantastic job too.

As Gemini and I developed see this, the future could unfold in two ways, depending on who owns and collects rent on this technology.

The optimist in me thinks that this technology will make most technological prowess by humans redundant and that would push tech to the background (all tech become trivial, like digital watches today) and we then get to focus on life, family, soil, water, nature, art, music, culture, sports, festivals and faith (faith is important), and that is best done in small close-knit rural communities. I live a life like this today and if we solve rural poverty, I consider this a very good life.

The pessimistic dystopian vision is centralized control.

Here is my Gemini chat session on this. You can continue the session on Gemini and see where it all goes.

■As per Railway Min @AshwiniVaishnaw , Travel time will be 2 hrs for BLR-HYD & 1 hr 13 mins for BLR-CHN.
■ However, Karnataka wanted High density , BLR-#Pune-#Mumbai line.
■ Request Railway minister to replace, Low density BLR-Chennai (about 2.5 Lac travelers per month), with #Bengaluru-#Pune-#Mumbai line, which is a high density Corridor with a potential of 14 Lac Travellers per month & which also covers most of Karnataka.
■ @CMofKarnataka , @DKShivakumar , Railway Mos @VSOMANNA_BJP
, Min @JoshiPralhad , @Tejasvi_Surya , @PCMohanMP , @ShobhaBJP @JagadishShettar @BSBommai are requested to take up this on priority.
■Note : Potential is calculated on the switch over Travellers from Normal Trains & Flights within these cities

For centuries, the Japanese valued freshness above all. Even freezing or keeping fish alive in tanks wasn’t enough- they lost taste, grew sluggish. The solution? Put a small shark in the tank. The fish stayed alert, alive, vibrant.

India too faces its “shark” moment when Trump slapped 50% tariffs. It’s an opportunity to push Make in India, diversified trade, and turn pressure into strength.

Comfort zones make us stale. Sharks- tariffs, competition, setbacks- keep us sharp. Let’s not fear them. They will keep us alive, fresh, and strong.

At some point, there needs to be a revision of the UN bodies.

Problem is that those with excess power don’t want to give it up.

India not having a permanent seat on the Security Council, despite being the most populous country on Earth, is absurd.

Africa collectively should also have a permanent seat imo.

Deep borewells are not a good solution anywhere, not California & not India. We have to rely on surface water and learn to live within the annual rain water budget or use desalinated water. I use the thumb rule of 10-15% of land area dedicated for ponds. Cooler microclimate too.
