There's a net new 80 million people added to the world every year.
It's already crowded af in large cities with ridiculous traffic, housing prices, crime, and air pollution (think LA, NYC, Hong Kong).
How much worse will it get before we start seeing a lack of food, energy, and resources (ie. metals) to sustain the population?
No. What do you think EVs do? What about renewables? Have these products and their means got more or less lifetime? How many more products does it take to make them work? How much more consumption are they offering?
This World has become insane. It cannot improve. It simply doesn't know how. It cannot not support more without more dystopia. All it wants to do is profit. It doesn't want to advance anything else.
You seem to have fallen for the Larp of hydrogen, electro-magnets, or God knows, in the other closet of cars can run on water, or ethanol. No. Those millennials are insane, how much more, for less. The freaking hydrogen system has how many more parts, generating much less, costing far more. It's like a dodo invented it. It will not keep up with the demand and it costs far more. Crops made into petrol. Nuts. How many more emissions has that caused? About 3 to 5 times more. Those plants, biomatter, the planet made into a fossil fuel. Suddenly there's this other dumb human, cannot use the planet's recycling, those fossil fuels, hell no, use this other biofuel instead, we recycled it. No it is not green, it has been made for idiots by idiots. Causing more consumption. Some dumb idiot needs the biofuel as another sale, it's sold right alongside the regular fuel. How much more do the EVs need to make them run? The more complicated a system the quicker it fails. Literally there's the weather. But it needs far more parts and services having far less lifetime. A combustion engine lasted decades, you could repair it yourself. A EV last less than a decade and it's replaced. The same with solar and turbines largely fair as bad. More consumption. More energy. More profit. Nothing to do with anything else.
This is the problem that I see.
Yes, the population can grow.
But it will mean more totalitarian control and dystopian way of life. It will not be a life worth living. I've already felt this way for 5+ years now, and it's only getting worse every year as more totalitarian controls are enacted.
A world with 9 billion people is not a world where you can fly by plane, travel by personal car, or not work dead-end slave jobs.
It is a world where you're a sardine squished on public transit and require anti-depressants so you don't jump under the train on your morning commute.
It implodes. The greater the population, the greater its problems caused. Becoming a tipping point.
It can gain greater numbers, often by advancing technology. However by changing any methods provokes the existing population not caught up. By continuously adding them into the current method causes it to tip.
The only means of adding them is by greater control, and it causes it to tip.
There is no solution. The Dystopia, has become abhorrent, like the current method adding them in to control them more. It tips. Those numbers will have to fall before they can ever hope to expand.
