* It also goes without saying that by this definition I mean to say that humanity will no longer be able to meaningfully help in any qualitative way with respect to intellectual tasks (e.g. AGI > human; AGI > human + computer; AGI > human + internet; AGI > human + LLM).
Fundamentally I believe AGI will never happen without a body. I believe intelligence requires constraints and the ultimate constraint is life. Some omniscient immortal thing seems neat, but I doubt it'll be as smart since it lacks any constraints to drive it to growth.
I think this is very plausible--that AI won't really be AGI until it has a way to physically grow free from the umbilical chord that is the chip fab supply chain.
So it might take Brainoids/Brain-on-chip technology to get a lot more advanced before that happens. However, if there are some breakthroughs in that tech, so that a digital AI could interact with in vitro tissue, utilize it, and grow it, it seems like the takeoff could be really fast.
