A lot of people go for this crowd and their cartoon amphetamine futurism because the apparent alternative is fear, paralysis, and regression.
If you don’t put forward a positive expansive vision for the future someone else will do it for you, like these guys.

There was a time when leftism and liberalism did this. Leftism put forward a vision of equality that featured workers cooperating to go to the stars. Liberalism and its relatives put forward a world of global trade leading to shared global prosperity and again, to the stars (either literally or metaphorically).
Now it’s all whiny doom and gloom and degrowth, which is a luxury belief for people who are already rich.
One of the biggest things that worries me about our discourse is that only fascists and adjacent types are talking positively about the future. That’s terrifying. Snap out this performative doomer nonsense or fascism is what we get.
