I’m not optimistic about it as a solution to climate change nor any current day energy needs primarily because it feeds right into the techbro/capitalist lame kink that if we just had wayyyyy more power it would solve everything. Most of the problems we are experiencing today stem from having too much power, too much capability to extract resources violently from the earth, too much power from oil to the point that we built a batshit insane transportation system based around cars (even in the center of the worlds largest and densest cities) and most importantly too much power in the hands of energy and fossil fuel companies.

Fusion would solve 0% of any of those problems, and the more people fixate on it as the kind of solution we should be holding out for to save us, the more dangerous it is.

However, the science is cool, it is definitely worth investing in and studying because one day it could be huge. I just think if we discovered an energy source that provided us with limitless power today, right now, it would actually be the precise thing that would doom the human race into not fixing any of the problems that truly threaten our survival as a species nor would it save the planet from us.
