This is why you can't gatekeep AI capabilities. It will eventually be taken from you by force. It's time to open-source everything. Papers, code, weights, financial records. Do all of your research in the open. Run 100% transparent labs so that there's nothing to take from you. Level the playing field for good and bad actors alike, otherwise the bad actors will get their hands on it while everyone else is left behind…
A "world where millions of AGIs run on millions of gaming PCs, where each AI is aligned with an individual human" would be a world in which people could easily create humanity-ending bioweapons. I would love to live in a less vulnerable world, and am working full time to bring about such a world, but in the meantime what you describe would likely be a disaster.
Intelligence itself is not dangerous unless only a few orgs control it and it's aligned to those orgs' values rather than human values. The safety narrative is just "intelligence for me, but not for thee" in disguise.
