That sentence sets off major alarm bells for me. Both Marxism-Leninism and Nazism had their "philosophical necessity" founded on some currently-popular philosopher. "It is philosophically certain that an AGI will be moral" is a mighty thin reed to base your safety on. If nothing else, there are other philosophers, and it is far from clear that yours is correct.
And, you want me to read up on the philosophy of how morality is embedded in physics? Yeah, how about we read up on the physics of it?
Mind you, I don't actually buy the "AI will kill us all" fear. I just think your argument here is specious.
