And it doesn’t cause other problems like outsmarting the brain systems that are supposed to be attaching your intelligence to the interests of your body? Or the people inconveniently stopping you from snorting cocaine constantly until you die? And there’s no level of intelligence you reach where you note that higher levels are unlikely to be any more use to you in achieving your actual goals, versus spending that button-pushing time on other tasks? And all this intelligence is free and doesn’t require any energy input to run in your head? And at some level you become intelligent enough to impart these abilities to your descendants or to just never die? And you reach a level of intelligence where you can fight off the CIA before you reach a level of intelligence where you interest the CIA?

People don’t generally reason about things like “intelligence” as an abstract value from zero to infinity, because we don’t encounter such things very often. What we do encounter is people trying to scam us. If you present someone with something that appears to be a 100% obvious perfect move with absolutely no drawbacks whatsoever, they mostly correctly conclude that they just aren’t smart enough to understand the catch.
