Can AI Help Save Pedestrian Lives in Our Cities?

The conversation around AI often focuses on saving lives through cancer detection, drug discovery, or autonomous vehicles. Yet one of the biggest opportunities may be much closer to home: helping ordinary pedestrians survive the daily chaos of urban streets.

Take Bengaluru. Even in relatively affluent areas like Indiranagar, a pedestrian faces a combination of hazards:

  • Potholes and broken pavements.
  • Encroached footpaths.
  • Delivery riders and couriers speeding on wrong sides.
  • Autorickshaws stopping unpredictably.
  • Poor street lighting.
  • Vehicles jumping signals.
  • Construction debris.
  • Stray animals.
  • Waterlogging during rains.

AI can help at four different levels.

1. AI as a “Pedestrian Guardian”

Imagine a smartphone app or smart glasses continuously scanning the environment.

It could:

  • Warn of approaching vehicles from behind.
  • Alert when a rider is coming the wrong way.
  • Detect open manholes, potholes, or broken footpaths.
  • Vibrate when a pedestrian is about to step into traffic.
  • Guide visually impaired or elderly users around obstacles.

Instead of reacting after an accident, AI would provide real-time risk alerts.

2. AI Mapping Every Hazard in the City

Every smartphone camera, dashcam, CCTV, and delivery vehicle can become a sensor.

AI can automatically identify:

The city would receive a continuously updated “pedestrian risk map” showing:

  • Potholes.
  • Missing footpaths.
  • Dangerous intersections.
  • Dark stretches.
  • Illegal parking.
  • Signal violations.
  • Streets with the highest accident probability.
  • Areas requiring urgent repairs.
  • Locations where streetlights are malfunctioning.

Instead of annual surveys, cities would have live intelligence.

3. AI-Powered Traffic Enforcement

Today’s traffic enforcement is largely manual

AI-enabled cameras can:

  • Detect wrong-side driving.
  • Identify red-light jumping.
  • Track repeated offenders.
  • Detect riding on footpaths.
  • Spot overspeeding near schools and markets.

Violations could be automatically documented and processed, increasing compliance without requiring thousands of traffic personnel.

4. AI for Urban Planning

The most powerful use of AI is not warning people about danger—it is removing the danger itself.

By analysing:

  • GPS traces,
  • pedestrian movement,
  • accident records,
  • CCTV feeds,
  • pollution levels,
  • lighting conditions,

AI can identify:

  • where zebra crossings are needed,
  • where footpaths should be widened,
  • where speed breakers are missing,
  • where signal timings are unsafe for elderly pedestrians.

The result is safer street design rather than simply safer behaviour.

5. AI for Senior Citizens

For older adults, who may have slower reflexes and reduced night vision, AI can be especially valuable.

A mobile assistant could:

  • Recommend the safest walking route rather than the shortest.
  • Avoid poorly lit roads.
  • Avoid roads with high traffic speeds.
  • Warn about uneven surfaces.
  • Share live location with family members during walks.

For a 70-year-old pedestrian, this could significantly reduce fall and collision risks.

The Bigger Question

The real challenge is not whether AI can identify potholes, rogue riders, or dangerous junctions. Technically, it already can.

The question is whether cities will use AI to prioritize pedestrians rather than vehicles.

For decades, urban technology has focused on moving more cars faster. The next generation of AI could instead focus on helping the most vulnerable road user—the person on foot.

In a city like Bengaluru, where a pedestrian often feels like an obstacle in the transport system rather than its primary beneficiary, that may be one of AI’s most life-saving applications.

The real question is not whether AI can do this.

The question is whether we are willing to use AI to prioritise pedestrians instead of vehicles.

Perhaps one of the most life-saving applications of AI won’t be in a laboratory or a hospital.

It may be on the footpath outside your home.

Climate Is Not the Only Wolf at the Door

A word for those of us who think “environment” begins and ends with carbon.

You care about the planet. That is admirable. You track carbon budgets, follow COP outcomes, argue for renewables, and push back on greenwashing. Good. Keep doing all of it.

But I need to tell you something uncomfortable.

Climate is not the only one wolf that is knocking at the door of Civilization. There are five others.

And while we stare at the climate wolf, the other five are quietly chewing through the door.

The World Economic Forum’s Global Risks Report 2025 surveyed over 900 global experts. State-based armed conflict ranked as the number one immediate risk. Misinformation and disinformation ranked number one on the two-year horizon. Climate and extreme weather events came third. The world is facing not a single crisis but a polycrisis. Multiple interconnected threats are amplifying each other.

Read that again. A polycrisis. Not a climate crisis alone.

Let us name all six wolves plainly.

Wolf One. Climate. Yes, it is real and it is urgent. In 2024, six of the nine planetary boundaries for environmental health were crossed, with a seventh in jeopardy. Tipping points are not coming. Many are here. This wolf is already inside the garden gate. But it is not alone.

Wolf Two. Debt. Global government debt exceeded $100 trillion in 2024, with the IMF projecting continued deterioration. When the next debt crisis breaks, and it will, it will defund every green initiative on earth overnight. Climate action costs money. Bankrupt governments do not fund green transitions. These two wolves hunt together.

Wolf Three. War. State-based armed conflict climbed from number eight to number one in the 2025 rankings. Ukraine. Gaza. Sudan. Taiwan tensions. A single blockade of the Strait of Hormuz disrupts global energy supply within days. Wars do not pause for net-zero targets. They burn forests, poison rivers, and release more carbon in weeks than most countries do in years.

Wolf Four. Technology without governance. As most governments opt for lighter-touch regulation and international cooperation falters, AI capabilities and risks continue to grow unchecked. Autonomous weapons. Engineered pathogens. Deepfakes deployed at scale. These are not science fiction. They are 2025 news cycles. A single bioengineered event could collapse societies faster than three decades of rising seas.

Wolf Five. The Truth Crisis. For the second year running, misinformation and disinformation tops the medium-term risk outlook. The severity score increased year-on-year, reflecting growing alarm about the intersection of artificial intelligence and information warfare. A society that cannot agree on what is real cannot act on any crisis. Including climate. This wolf does not just threaten the environment. It paralyses the response to every other threat.

Wolf Six. Water, Food and Demographics. Aquifers are depleting silently beneath our cities and farms. Topsoil is eroding faster than it forms. Pollution is the world’s largest environmental risk factor for premature deaths, with 92% of pollution-related deaths occurring in low and middle-income countries. This is not a future scenario. It is today’s lived reality for billions. Climate change accelerates it. But it exists independently of carbon alone.

Now here is the hard truth about single-issue environmentalism.

When we frame every conversation through only the climate lens, we alienate the farmer in Punjab who is drowning in debt. We lose the factory worker in Gurgaon worried about his job disappearing to AI. We miss the policymaker in Singapore calculating energy security tradeoffs. We speak only to the already converted. And we leave the door wide open for the other five wolves.

As nations increasingly prioritize national interests over collective action, pressing questions emerge about the capacity of the international community to confront shared challenges such as climate change, global health, and economic stability.

Collective action is impossible when people feel their immediate survival is not part of your agenda.

The climate movement needs to grow up strategically. Not abandon its mission. Grow it.

Connect climate to food security and you reach a billion farmers. Connect it to sovereign debt and you reach finance ministries. Connect it to conflict and you reach defence establishments. Connect it to water and you reach every mother on earth. Frame climate as one thread in a larger civilizational fabric and suddenly the conversation reaches everyone, not just those who already agree with you.

The WEF’s own framing says it best. The global risks landscape reveals an increasingly fractured world, where escalating geopolitical, environmental, societal and technological challenges threaten stability and progress simultaneously.

Simultaneously. Not sequentially. Not one at a time.

Six wolves. One door. One civilization.

Wearing a raincoat is smart when it rains. But if your house is also on fire, your neighbors are fighting, your bank account is empty, and someone just hacked your security system, a raincoat is not enough.

We need people who can see all six wolves at once.

We need thinkers, activists, investors, farmers, engineers, and diplomats who stop asking “is this a climate issue?” and start asking “how do all these risks connect, and where do I stand in that web?”

Because the wolves do not fight each other.

They hunt in a pack.

Which wolf haunts you the most—the one that keeps you awake at night? Share your thoughts in the comments.

The Digital Estate: How I Used AI to Turn 2 Terabytes of Chaos into a Travel Legacy

The art of travel, as any wanderer knows, is not merely in the going, but in the keeping and sharing memories. We move through the world, across the velvet plains, hills, volcanos, glaciers, deserts, oceans of seventy plus countries and the salt-sprayed edges of seven continents, gathering glimpses of the eternal like pebbles in a pocket. For years, my pockets have been digital— a lineage of silicon and glass stretching from the humble, earnest clicks of a Kodak EasyShare to Nokia 73 to Galaxy Ultras to the folded miracles of the Samsung Fold 7 and the heavy, soulful weight of Nikon and Canon mirrorless glass.

I have never claimed to be a photographer; I am simply a witness. Yet, witnesses are messy.

The Weight of Unseen Worlds

Over the decades, my wife and I have accumulated a digital ghost-library: 2 terabytes of raw light and sound. It was a labyrinth of folders—some titled by country, others merely by the name of the camera that bore witness to the scene. It was a cartographer’s nightmare. Every time I considered organizing this mountain of memory, I felt a shivering inertia. To touch those files was to be buried by the sheer volume of our own history.

The reckoning came not from a sense of order, but from a sense of mortality. While updating my Will, I realized that these files are not just data; they are my digital estate. They are the artifacts of a life lived in motion. If I did not curate them now, they would remain locked in silence forever.

The AI Intervention

A consultation with the digital oracles (DeepSeek) suggested a way forward: transform these static assets into a YouTube channel. It was the perfect vessel—a way to preserve, share, and perhaps even breathe a second life into these moments.

I hired a young enthusiast to help with the alchemy of editing, but when he saw my chaotic folder structure, he nearly pulled his hair out in despair. The bridge between my raw past and a polished future seemed impassable.

That is when I turned to Claude. If AI could not yet broker peace in our fractured world, it could, at least, bring peace to my hard drive. Within thirty minutes, it provided me with a Python script—a digital loom that wove through the metadata of my chaos.

The Great Sorting

The script was elegant in its ruthlessness. It filtered my life through a logical sieve:

  • Hierarchy: Country → Year → Month.
  • The Sift: Files were automatically sorted into “Accepted” and “Rejected.”
  • The Standard: Anything shorter than five seconds or lower than 720p was cast aside, deemed too fleeting or too blurred for the legacy I wished to leave.

A New Horizon

The proof was in the processing. Last week, we returned from the misty heights of Patnitop and Vaishno Devi, armed with 50 GB of fresh memories across three different cameras. In the old world, it would have taken days of squinting at thumbnails to sort the wheat from the chaff.

In this new world? It took two minutes.

The “shivers” are gone, replaced by a quiet, rhythmic pulse of progress. The labyrinth is becoming a gallery. Now, finally, the stories we gathered across seventy countries can begin to find their way home.

From Climate Faith to Energy Realism: A War I Didn’t See Coming

I was wrong. And I am furious.

For years, I stood on every platform and told everyone that green energy was our salvation. I told all that solar panels and wind turbines were the silver bullets. I told the policy makers that if we just banned oil fast enough, the climate crisis would be solved. I called anyone who doubted it a spokesperson for Trump and Big Oil. I sold all fossil fuel stocks from my equity portfolio.

Today, after straightjacket on strait of Hormuz, I’m eating crow. And it tastes like diesel and coal fumes.

I went in as a believer. I came out a skeptic—not because I hate the planet, but because thanks to Peter Zeihan’s “The End of the World is just the Beginning”, I finally looked at the actual physics and chemistry of how we live. I am angry at myself for lying to all. I am ashamed I didn’t read this data sooner.

We have been sold a fairy tale. Here is the brutal truth about why we are NOT leaving petroleum any time soon.

First: Oil isn’t just gas in a tank. It’s everything you own.

I used to think 80% of oil went to cars. Wrong. Nearly 20% of global oil demand is for petrochemicals—lubricants, bitumen, and the building blocks of modern life. Look around your room right now. Your shoes? Made possible by oil. Your phone case, your Intra Venous bag at the hospital, your detergent, your diapers, your tires, your insulation, your paint? All oil.

Here is the killer blow: moving away from these fossil-fuel inputs would cost ten times more and create a carbon footprint ten times larger. There is no “green” plastic. There is no solar-powered shoe factory. We either use oil, or we go back to living in a world without medicine, without packaging, without modern clothing. I am not willing to watch my family die of an infection because we banned petrochemical derived antibiotics.

Second: My EV is a toy compared to a diesel earth excavator, a JCB or a road roller.

I know I love my Ioniq 5. You may love your Tesla. But we have been lying about “heavy lifting.”

Oceanic shipping? There is no battery on planet Earth that can recharge a container ship in the middle of the Pacific. Heavy farm equipment? A combine harvester works 18-hour days during harvest. Batteries die in four hours. And to convert the entire global transport fleet to electric, we would need to double humanity’s current electricity generation. Doubling. Where does that power come from? More fossil fuels? We are running in circles.

Third: Without oil, billions starve. Today.

This is the one that broke me as I come from Food industry. I used to say “eat less meat to save the climate.” I was missing the forest for the trees.

Modern agriculture is a petroleum machine. Diesel runs the tractors. Oil is the primary ingredient for pesticides, herbicides, and fungicides. Without those chemicals, crop losses would be catastrophic. And natural gas—often a byproduct of oil drilling—is the central ingredient for nitrogen fertilizer. No fertilizer? No rice. No wheat. No feeding 8 billion people.

If we shut down oil refineries tomorrow to save the climate, we wouldn’t have a green utopia. We would have a famine within 12 months. I now refuse to be the activist who trades a warmer planet for a dead one.

Fourth: Green tech is geography’s lottery, not a solution.

I used to scream “Build more wind! More solar!” But here is the dirty secret: most of the world is neither windy nor sunny enough to make this work. In many regions, building a massive solar farm actually emits more carbon than it saves because of the concrete, mining, and shipping required. I live on the ground floor of a multi storey apartment building. I cant install a solar system. Can you?

And the intermittency? Oil is energy storage. You drill it, you refine it, you put it in a tank, and it sits there for months, ready to burn. The sun doesn’t always shine. The wind doesn’t always blow. But a barrel of oil works 24/7, rain or shine, hurricane or heatwave. Imagine the number and size of batteries to store electricity generated by solar or wind. Mind-boggling numbers. Then the grid. Where you put up industry grade solar system and where the electricity is consumed (cities) are miles apart. Long distances. Grid and tranmission wires need steel. Steel need mining and coal. Think of mining equipment. The list of materials and manufacturing powered by fossil fues is endless. Think of peak demand in summer nights and winter colds. Sorry sun doesn’t shine during nights. A diesel generator may perhaps help.

The shameful conclusion.

I became a non-believer because I finally realized that petroleum isn’t a “dirty fuel.” It is the foundation of civilization as we know it now. It allows us to ignore geography, to move mountains, to grow food in deserts, and to keep 8 billion people alive.

A sudden move away from oil without a replacement doesn’t cause a recession. It causes decivilization. A cascade of breakdowns where the grid fails, then the food system fails, then the hospitals fail, then the water pumps fail.

I am not saying “burn coal forever.” I am saying I was a fool for promising you a quick fix. Green energy is a supplement, not a replacement. And until battery density improves by a factor of ten, until we invent a non-petroleum plastic that costs the same, and until we find a liquid fuel as energy-dense as diesel…

We are oil’s tenants. And we aren’t moving out.

I’m sorry I lied to you. I’m angrier at myself than you could ever be. I am rebuking coal and oil stocks.

I am also buying Uranium stocks.

ELECTRICITY DERIVED FROM NUCLEAR ENERGY IS WHAT WILL SAVE US EVENTUALLY. IT IS CLEAN. IT IS COMPACT AND DENSE. IT CAN DO EVERYTHING THAT FOSSIL FUEL DO. JUST FEW TONNES REQUIRED ANNUALLY TO RUN CITIES AND COUNTRIES. JUST DO THE MATH. ASK CHATGPT.

Hiroshima and Chernobyl suddenly seems to be a lesser price to pay than total extinction.

Thanks to Trump – A former believer, now a furious realist.

What happens if globalization begins to unwind?

As conflicts in the Middle East threaten critical shipping routes and geopolitical trust erodes, the question is no longer theoretical: what happens if globalization begins to unwind?

Coming from a food supply chain background, I ran a thought experiment to test this theoretical premise.

Imagine for a moment that India is the entire world, and its states and Union territories are independent countries. Now imagine those borders suddenly turn hostile. Trade stops. Trucks halt. Ports close. Supply chains fracture.

Punjab grows wheat, Karnataka supplies millets, Maharashtra produces fruits, Andhra Pradesh sends seafood, and Uttar Pradesh provides vegetables and so on. Every day, millions of tonnes of food move across invisible borders to feed cities like Delhi, Mumbai, Chennai, Kolkata, and Bengaluru.

Within days, India’s largest cities—designed to function on deep interdependence rather than self-sufficiency—would face an uncomfortable question: how long can they feed themselves?

This thought experiment may sound dramatic, but it mirrors the fragility of the globalized system that runs the world today.

The Premise: “Bharat” is No More

In our current reality (Pre-Disintegration), the five major metropolitan cities are parasitic engines. They generate GDP and services but are utterly dependent on a national hinterland for survival.

  • Mumbai: Relies on Gujarat (Peanuts, Onions, Milk), Karnataka (Mangoes, Vegetables), and Punjab/Haryana (Wheat).
  • Delhi-NCR: The biggest consumer of Punjab and Haryana’s “Green Revolution” belt (Wheat, Rice, Milk).
  • Kolkata: Dependent on the Eastern belt—Bihar (Vegetables), West Bengal (Fish, Rice), and the Northeast (Fruits, Spices).
  • Chennai: Relies on the “Rice Bowl” of Tamil Nadu itself, but also Andhra Pradesh (Chillies, Vegetables) and Kerala (Coconut, Tapioca).
  • Bengaluru: The Silicon Valley that eats food from Andhra Pradesh (Tomatoes, Rice), Tamil Nadu (Dairy), and Kerala (Coconut).

In our “Anarchy India,” the trucks stop at the borders. Let’s see how each city collapses.

The Worst-Case Scenario: Survival of Each City

1. Delhi (The Nation of “Dilli”)

  • Dependence: 90% reliant on Punjab (Wheat) and Haryana (Milk, Vegetables).
  • The Shock: Overnight, the “Nation of Hariana” and “Nation of Punjab” seal the borders. They have the grain, and they have no reason to trade with Delhi, which offers only services and bureaucracy.
  • Survival Food: The Yamuna floodplains. The small-scale vegetable farming on the riverbanks will become a warzone. The city will survive on “Bathua” (Lamb’s Quarters) and wild greens growing in abandoned lots.
  • Population Outcome: Mass Starvation (60% decline). The population that survives will be the one with access to the rural fringes (West Delhi, Narela) that can turn to subsistence farming. The rest will fight over grain reserves until they run out.

2. Mumbai (The Nation of “Bombay”)

  • Dependence: The city is an island. It depends on the Konkan for fish, but staple grains (Rice) come from the South, and Vegetables from the Nashik district (which is now in a different “nation” of Maharashtra, but cut off by internal borders).
  • The Shock: Maharashtra state, as a unified entity, breaks into rival factions (Mumbai City-State vs. Western Maharashtra vs. Vidarbha). The highways are blocked.
  • Survival Food: The Arabian Sea. Mumbai will revert to a fishing village. The Koli community (original fisherfolk) will become the ruling class. They have the only protein source.
  • Population Outcome: Coastal Attrition (50% decline). Starvation will be rampant, but the city might survive slightly better due to the sea. However, without rice from the mainland to eat with the fish, malnutrition (protein without calories) will cause massive health issues.

3. Kolkata (The Nation of “Kalikata”)

  • Dependence: The “Rice Bowl” is right next door (Bangladesh in reality, but in our scenario, Bardhaman and the Sundarbans are now potentially hostile).
  • The Shock: The Ganga/Bhagirathi river system is the lifeline. If the upriver nations (like “Bihar”) dam the water, Kolkata loses not just food but fresh water.
  • Survival Food: The Sundarbans delta. Fish, crabs, and mangroves. The city will turn to the backwaters.
  • Population Outcome: The Wetlands Scramble (40% decline). Kolkata might actually fare best in terms of calories because the delta is rich. However, the lack of potable water due to upstream damming and saltwater intrusion will cause a cholera and dysentery epidemic, killing more than hunger.

4. Chennai (The Nation of “Madras”)

  • Dependence: Highly dependent on the Cauvery River water and surrounding districts for rice.
  • The Shock: The age-old Cauvery water dispute turns nuclear. The “Nation of Karnataka” upstream cuts the water to the “Nation of Tamil Nadu.” Chennai dries up.
  • Survival Food: The coast and the remaining tanks (ponds). They will survive on tapioca and fish.
  • Population Outcome: Thirst and Hunger (55% decline). Chennai will be hit by a dual crisis: lack of water for drinking and lack of water for irrigation in its peri-urban farms. The city will be the first to experience complete societal breakdown due to fights over water tankers.

5. Bengaluru (The Nation of “Bengaluru”)

  • Dependence: The most vulnerable. It is a city built on a rocky plateau with no river. It imports everything: Milk from Mysore, Vegetables from AP, Water from Cauvery.
  • The Shock: The “Nation of Andhra” stops tomato trucks. The “Nation of Tamil Nadu” cuts power (if the grid is split). The “Nation of Mysore” stops milk.
  • Survival Food: Ragi (Finger Millet). It is the only crop that grows naturally in the dry, rocky Deccan plateau. The city will survive on Ragi mudde (balls) and whatever can be grown on terraces.
  • Population Outcome: Tech Collapse (70% decline). Bengaluru has the least arable land within its immediate municipal limits. It will become a ghost city faster than any other. The IT corridors will become empty concrete jungles.

The Broader Consequences (Beyond Food)

If this happens in India, it is a mirror of what happens when Globalization ends globally. Here are the macro-level consequences:

1. The End of Dietary Diversity

  • Current: A person in Delhi can eat an apple from Kashmir, fish from Bengal, and tea from Assam.
  • Post-Collapse: You eat only what your climate allows.
  • Effect: In the “Nation of Ladakh,” people survive on barley and meat. In the “Nation of Kerala,” they have spices but no grain to cook. Global nutrition plummets. Vitamin deficiencies (Vitamin C, B12) become rampant globally as citrus and fortified foods vanish.

2. The Weaponization of Perishability

  • Current: Milk, meat, and vegetables move in a “cold chain.”
  • Post-Collapse: Nations with dairy (Punjab, Haryana) have surplus milk, but without packaging from Gujarat or transport fuels, it spoils in hours.
  • Effect: The world shifts to an economy of only non-perishables. Only grains, salt, and dried legumes trade. Fresh food markets vanish. Global health declines as processed, shelf-stable food becomes the only currency.

3. The Water Wars (The Cauvery and Indus Syndrome)

  • Current: Rivers flow through multiple states/countries.
  • Post-Collapse: Upstream nations build dams.
  • Effect: Downstream nations (like Bangladesh in real life, or Sindh in Pakistan) become deserts. Mass migration of “climate refugees” happens not because of climate, but because of hostile neighbors starving them out.

4. The “Brain Drain” Reversal

  • Current: People move to cities for jobs.
  • Post-Collapse: People will try to flee cities to find farms.
  • Effect: The “Service Economy” dies. If you are a coder in Bengaluru but there is no food, your skill is worthless. The world reverts to a barter economy based on agrarian output. Doctors and engineers will trade their skills for a bag of rice.

5. The Pharmaceutical Crisis

  • Current: Hyderabad (Bulk Drugs) and Gujarat (Chemicals) supply India and the world.
  • Post-Collapse: These “nations” are cut off.
  • Effect: Diabetics in Mumbai run out of insulin. Asthmatics run out of inhalers. The mortality rate spikes not just from hunger, but from the lack of chronic disease management. The world realizes that “Global Health” is entirely dependent on a few chemical hubs.

The Verdict: A Mirror to the World

If India breaks up, the five cities survive only if they revert to their pre-industrial, pre-colonial identity:

  • Mumbai becomes a fishing village.
  • Delhi becomes a small agrarian town on the Yamuna.
  • Bengaluru reverts to a pensioner’s retreat with Ragi fields.

The thought experiment proves that Globalization is not a luxury; it is a life-support system.

When it ends:

  1. Cities die.
  2. Populations crash to match the local carrying capacity of the land.
  3. Conflict becomes perpetual (wars over grain silos and water).
  4. Human longevity decreases (due to lack of medicine and nutrition).

The “End of Globalization” essentially means the end of the complex, interconnected organism that allows 8 billion people to live. The world would regress to a medieval patchwork of survival, where a tomato on a table in London is a miracle of diplomacy, not just logistics.
