That being said, I'm convinced we continue to deeply underestimate the intelligence and competence of numerous species, even today when we like to talk about how ridiculously smart dolphins and whales and dogs and birds and primates etc... are.
I remember thinking, "I will be that dad who does not underestimate my kids capabilities. I won't hold them back." And my 5yo is still absolutely blowing me away with his ability to build complex redstone machines in Minecraft. I think humans are just really good at underestimating competence.
