The reality of course falls short of the most optimistic projections, but e.g. for batteries: look around! Wealthy countries at least are now full of little gadgets that couldn't have existed even a few years ago due to the battery demands. A walk down any street in NYC you'll see probably 5-8 different personal transportation systems that are pretty close to sci-fi.
- simonh 4y agoI agree on batteries, but something like half a dozen Manhattan projects worth has been spent on fusion research so far and we don’t seem anywhere remotely close to achieving even a fraction of its promise. I remember reading about the future of fusion energy in my teens, and now my daughters are coming out of their teens. And I had kids late. I’m sorry but technical break even just doesn’t cut it for me at this point.
