i mean, this dude is just spouting bullshit, but yes, in a way. it'd be better to say that the gnostics were describing the proto-capitalist roman imperial slave-based system that eventually evolved into modern capitalism. but the early ecumenical conflicts and subsequent violent repression of so-called gnostic heresies were, imo, mostly about control of the early christian anti-imperialist movement and figuring out how to synthesize it with the existing roman power structures, a process that took 300 years.

in modern terms, the demiurge is the paperclip-making super ai, a blind, unthinking, extremely powerful entity of human creation but no longer under human control. and capitalism is certainly that.
