How have we underestimated them? We’ve absolutely dominated every single ecosystem that we push in to. We’ve long ago destroyed all of the minds that could have possibly challenged us, all the other members of the Homo family. The reason humanity makes an estimation that we’re the smartest is because for the last 40,000 years, it’s been the truth, proved over countless eons.

Being smart and being capable are two different things. Human beings are very capable

Being smart is a waste of calories if you don't use it to become more capable. At least in evolved systems, I wouldn't expect to find intelligence without capability.

I do think that human beings owe a lot two their two hands and fingers (besides their smarts). Even if a dolphin or an orca is indeed very smart, they will never be as capable as a human due to their physicality.
