I think the logic here is supposed to be something like:

more knowledge = more complex brain

as you need to “store” the knowledge somewhere.

I don’t say thats how it works but i can somehow see where OP is coming from.

Im generally interested, and would love to see one getting created, even if i am not in the position to participate in such a community right now as a new parent.

The community on the android app “sketch a day” was pretty nice last time i was around. I know its not the same, but maybe a temporary fix? :)
