I mostly agree with what you said here. I'm constantly reminding people I know that its called the
petrochemical industry because its about far more than just fossil fuels, you can't unwind the need for advanced chemicals in modern society, the population is just too big for us to realistically unwind our need for e.g. the Haber-Bosch process without major advances, and both the pharmaceuticals industry and high tech are completely dependent on extremely complicated oil-based supply chains. Many people will at this juncture reply that we just need less people, but thats not really an ethical solution by any modern standard.
>susceptible to being wiped out globally by a single unforeseen threat
I'm actually pretty optimistic about this, I think that we have enough people and growing standards of education, that assuming the technological solutions are out there, we will probably find them. The only threat that we aren't taking seriously that would really screw us up is some sort of cosmic event (I am very frustrated that with all the talks of creating a more flexible grid for renewables we aren't taking on the added burden of hardening against a solar storm, which seems inevitable. I'm pretty sure we would be pretty screwed if another Carrington Event happened today.[1])
>"democracy is the voice of the people" argument.
Serious question, is this really a point of view that people have in serious circles? I don't know a single person who believes that the US doesn't suffer from a burgeoning plutocracy. I've been calling this the second guilded age for years now, and it only seems to be getting worse. There is no Teddy Roosevelt figure rising that I see. I can only hope that the next generation of politicians will take reigning in this monster more seriously, but I'm skeptical.

I feel like something of this magnitude would be enough of a setback on science, in many ways, that all hope might be lost of escaping the terminal state we have put the earth into.
