Kinda like alpha go zero but with "life".
If a bunch of AIs started discussing with each other, and learning from each other, without validation, things can go wrong very easily.
I bet a lot of people thought that strapping a pair of feahterry wing was all that's needed to fly. This "knowledge" could've passed from one person to another through discussion. But it only took one (or more) person to actually try it in the real world to learn that, no, that doesn't work like that.
AI communities (as in communities of AIs talking to each other) might be one filled with the most outrageous "conspiracy theories", that may sound plausible but have no substance.
How can you assert this ? Do you have any evidence?
In the latter case, the first humans (H. Habilis) had about 1/2 of H. Sapiens brain to work with, and a much smaller fraction of neocortex.
If that doesn't satisfy you, let's say I was speaking about some sort of human ancestor before that, which would have been about as dumb as chimps, unless you require proof of their dumbness as well.
All the new knowledge they got they figured out from the environment.
