I agree with the definition that intelligence is the ability to create knowledge from information. Therefore even the creation of harmful knowledge requires intelligence. What baboons probably have more of than humans is wisdom. Wisdom is about creating useful knowledge. Wisdom tells us when our intelligence shouldn’t be used.

I agree with you, though, that human knowledge is profoundly limited. I’m constantly confronted by the limits of humans around me to comprehend the existence of nonhuman culture. It’s only a limit of their intelligence insofar as intelligence is a choice. Which, I think, in a lot of ways it is.
