late to the party, but we are already verging on the dystopian futures we were warned about in entertainment media for decades.
Our resource use per person is growing seemingly exponentially. We are going to reach a point where solar is going to be our only actual source of reliable energy to feed the needs. Unless we as people entirely change the way we handle things, we are going to need to make dyson swarms, or rings to funnel energy directly to earth in a more usable format from the sun.
I personally think that greed and power, will prevail and we will never get to a "post scarcity" utopia like star trek. the reality to me thats more likely is we will just sort of merge solarpunk, and our current cyberpunk, into our own real dystopian deal.
I prefer the highly idealized 1950/1960 future world that solarpunk art seems based on....And its always been my dream since a kid to live in that world we were promised...but I just dont see that happening.
