As mentioned in the article, Andreessen's "techno-optimist manifesto" cited Marinetti - one of the coauthors of the original fascist manifesto - as one of his inspirations

The claims of fascism almost all ultimately go back to Nick Land and his stupid writings. The guy is just fashionable nonsense/cultural marxism for the tech-bro. There's almost no other ring wing representation at all within critical theory, and Land is marginalized within those communities. I wish that Mark Fischer had captured the same kind of cultural capital that Nick Land has before he killed himself, because I expected Mark Fischer to be beloved from the "AGI now"/E/acc-ers crowd.

I don't care how unpopular what I'm about to say is becasue it's true, but most "E/acc-ers" are ultimately looking for a world like star-trek, though even they admit it'll look most closely to DS9. I know of almost none who serious advocate for any kind of fascism.

No I don't feel like quibbling about the definition of fascism or the extent to which tech accelerationism is right wing. It's not a novel observation or unique to me, I'm sure you can find some primers if this is the first you're hearing about it.
