A lot of us have been pointing this out for years. I've been called "stupid" and "short-sighted" when I've brought it up
Really, short-sighted? It's pretty fucking obvious to me that short-sighted is just assuming men in white lab coats or the market are going to solve your problems. Too many humans consuming too many resources to maintain a lifestyle that is (in most places) too high.
You can switch and shuffle around your source of energy all you like, but you're always gonna hit the cap of the most limited resource to make that technology possible
Pretty fucking obvious
The only thing that looks remotely promising is Thorium-Fluoride reactors, but that won't really help with the water crisis, liquid-fuel crisis, food crisis, etc
Too many people, people. Malthus is back in style!
I'm still waiting for the advent of the computer science groupie.
