Let's put it this way: If in our lifetime we can simulate the intelligence of a vinegar fly as general intelligence, that would be a monumental landmark in AGI. And we're far, far, far away from it.

I get what you mean here and I agree with it, if we're talking about current "AI", which isn't anywhere close. I know, because I've programmed some simple "AIs" (Mainly ML models) myself.

But your comparison to ancient egypt is somewhat lacking, considering we had the aptly named dark ages between then and now.

Lot's of knowledge got lost all the time during humanity's history, but ever since the printing press, and more recently the internet, came into existence, this problem has all but disappeared. As long as humanity doesn't nuke itself back to said dark ages, I recon we aren't that far away from AGI, or at least something close to it. Maybe not in my lifetime, but another ~2000 years seems a little extreme.
