Between topsoil depletion, fresh water scarcity, usable sand and precious metal scarcity, and ocean acidification leading to an eventual possible extinction of all edible seafood, it's looking like we aren't going to be able to just keep building new tech to keep supporting our current population, especially at the rampant level of consumption companies have been training them on (nevermind a perpetually increasing population).
And likely we're going to start running out of these things (and others) in certain locations, and eventually everywhere, if we don't find the will to completely reverse course (and it's clear there's been no real will to do so by those in charge). Conversion to electric cars and solar panels just improves the CO2 problem, it doesn't address the rest.
I like Vitalik and own Ethereum and I love technology, but I still don't see anything that's likely to resolve the fundamental problem that we're just using resources way, way faster than they can be replaced on this finite planet, and eventually it's going to catch up to us, short of some form of major human cataclysm (like a super pandemic or something) that happens before resources start running out.
