What Will Happen In 2100 And Cities, AI, And Life In The Next Century

Looking into the very distant future is always a crazy gamble. A hundred years ago, normal people thought we would be flying to work. They dreamed of personal jetpacks. They were completely wrong about the jetpacks. They never predicted the massive internet, either. Trying to guess exactly what will happen in 2100 requires looking closely at current science. It requires pushing that science to the absolute extreme limits. 

The tiny children being born today will actually see this distant year. They will be elderly citizens living in a completely alien world. The world will look totally different to us. The changes coming are absolutely massive. The global population is exploding rapidly. The earth’s climate is throwing brutal, violent tantrums. Advanced computers are literally learning how to think. The next century will force humanity to adapt quickly. If we fail, we face terrible consequences. The bold predictions are a wild mix. They contain terrifying global challenges and amazing technological miracles. 

Packed Cities And Sky Farms

Open space on Earth is running out very fast. Smart experts predict the human population will peak soon. It will hit around 10 or 11 billion people by the end of the century. Most of these future humans will abandon rural countryside completely. They will pack tightly into massive, sprawling mega-cities. 

Giant cities in Africa and Asia will grow to impossible, staggering sizes. A single city might hold fifty million people easily. Housing everyone will require building massive skyscrapers. These huge towers will literally touch the dark clouds. The biggest problem is actually food, though. Ten billion hungry stomachs require a ridiculous amount of green farmland. We simply cannot just chop down more forests to grow simple corn. 

The bright solution is vertical farming. Giant glass towers will grow fresh food entirely indoors. They will use specialized pink LED lights instead of the hot sun. They will use tiny misting tubes instead of dirty soil. These robot-controlled super farms will run twenty-four hours a day. They will be totally immune to terrible droughts or freezing snowstorms. The fresh food will travel an easy elevator ride down to the local grocery store. It will no longer ride on a dirty diesel truck for thousands of miles. 

Weather Shifts And Big Walls

The global climate problem is the giant dark cloud hanging over the future. When discussing what will happen in 2100, the weather is the scariest variable. The entire planet is trapping heavy heat. Massive ice sheets in the frozen polar regions are melting fast. They are pouring straight into the ocean. 

This rapidly melting ice raises the sea level dangerously. Flat coastal cities are in serious, immediate danger. Famous beautiful places like Miami and Venice might face constant daily flooding. Parts of New York are also at risk. Humans will not just abandon these incredibly expensive cities easily. They will fight back aggressively with thick concrete. Massive sea walls will surround coastal towns. Giant mechanical floodgates will protect the expensive real estate. 

Humanity will likely stop burning dirty fossil fuels entirely by then. The massive global shift to solar panels will be complete. Wind turbines and advanced nuclear fusion will power everything. The air will actually be much cleaner in 2100 than it is today. The thick brown smog will disappear from Los Angeles. It will vanish from Beijing. The trapped heat already sitting in the atmosphere will cause problems, though. It will make extreme hurricanes and wild heatwaves a very normal part of summer life. 

Computers Thinking Faster Than Us

Artificial Intelligence is just a clumsy toddler right now. By the end of the century, AI will be an absolute monster of pure intelligence. Computers will not just follow strict, boring code. They will think freely. They will reason deeply and invent crazy things on their own. 

This insane level of computing completely changes the foundation of human society. Smart robots will handle all the dangerous jobs. They will do the dirty and boring tasks. Nobody will risk their fragile lives working in deep underground coal mines. Robots do not need fresh oxygen. They never complain about working incredibly long shifts. 

• Self-driving transport: Human drivers will be strictly outlawed on fast highways for safety reasons.
• Instant construction: Swarms of flying building drones will 3D-print entire apartment buildings in days.
• Brain connections: People might have tiny computer chips that link their minds directly to the internet.
• Virtual reality: Boring schools and regular offices will exist entirely in perfectly realistic digital worlds.
• Robot companions: Friendly machines will take care of the elderly. They will provide medicine and daily conversation.

Some nervous people fear the smart machines will take over completely. Others believe AI will just be a massive, helpful tool. It will solve impossible math problems quickly. It will cure complex human diseases in seconds. 

Fixing Bodies With Tiny Machines

Big hospitals in the next century will look exactly like science fiction movies. The old days of cutting people open with crude steel scalpels will seem totally barbaric. Advanced medical science will operate on a microscopic level. 

Engineers are currently developing amazing nanobots. These are tiny robots the exact size of red blood cells. A smart doctor will inject a million of these tiny machines into a sick patient. The tiny nanobots will swim through the human veins. They will hunt down deadly cancer cells. They will destroy the bad cells one by one. They will repair damaged heart valves directly from the inside out. 

Organ donation waiting lists will disappear completely. If a person ruins their poor liver, the hospital will just print a new one. They will take a simple swab of the patient’s own DNA. They will grow a fresh, perfect liver in a clean lab within weeks. Because of these insane medical leaps, the average human lifespan will skyrocket. Reaching 110 years old will be completely normal. People will stay very active and extremely healthy for decades longer than they do today. 

Packing Bags For Mars

Earth is just a single, fragile basket. Keeping all of humanity in one single basket is a terrible survival strategy. A giant space asteroid could ruin the planet. A massive super volcano could destroy everything. By the turn of the century, humanity will be pushing very hard into deep space. 

A permanent human colony on the dusty surface of Mars is highly likely. It will definitely not be a luxury resort. It will be a harsh, dangerous underground bunker. It will protect brave scientists from deadly space radiation. It will be a real, functioning city on another rock, however. 

Space travel will drop in price massively. Giant reusable metal rockets will take off daily. They will land exactly like commercial airplanes. The rocky Moon will have heavy mining bases. These bases will extract rare, valuable metals. Wealthy space tourists might spend their honeymoons floating in zero-gravity. They will stay in giant hotels orbiting the Earth. Humanity will finally become a true space-faring species. 

Working Less And Playing Harder

With smart robots doing the heavy lifting, things will change. AI will do all the complex math. The basic nature of human work will shatter completely. The traditional forty-hour workweek will look like a cruel, ancient joke from the past. 

People will likely work much less. Society will have to invent entirely new ways to distribute money and raw resources. Universal basic income might be the very best way to keep the global economy moving. It will be needed when robots do all the actual paying jobs. 

Humans will spend their extra time focusing on extreme creativity. Beautiful art, loud music, and bizarre new sports will dominate culture entirely. People will build massive digital universes just for fun. When basic daily survival is finally guaranteed by machines, humans will thrive. They will finally have the absolute ultimate luxury. They will have free time. 

Bringing Nature Back To Life

Advanced technology will not just save fragile humans. It will actively save the precious wildlife humans almost destroyed. The end of the century will see a massive global push. It will be a huge push for global rewilding. 

Because humans will pack tightly into dense mega-cities, vast stretches of land will empty out. They will be totally abandoned. Nature will violently reclaim the cracked concrete. Smart governments will tear down old, totally useless highways. They will plant trillions of genetically modified trees. These super trees will suck bad carbon out of the air at triple the normal speed. 

Scientists will use advanced DNA cloning. They will bring back amazing animals that recently went extinct. Swarms of solar-powered drones will patrol the deep oceans constantly. They will scoop up floating plastic trash. They will break the ugly plastic down into harmless dust. Technology and wild nature will finally merge safely. The planet will be carefully managed exactly like a giant, beautiful botanical garden. 

Looking Down The Long Road

The rough journey to the next century will be incredibly bumpy. There will be massive natural disasters. There will be bad economic crashes and terrible human mistakes along the way. Humanity is a very messy species. We always learn hard things the hard way. The huge potential for a brilliant future is right there, though. When looking at what will happen in 2100, the ultimate feeling should be hope. The wild inventions being built in dirty garages right now will eventually cure terrible diseases. They will cool the hot oceans. They will carry humanity straight to the stars. The future is going to be wildly different. It just might be completely magnificent.
