You'd be surprised what the AVERAGE human fails to do that you think is easy, my mom can't fucking send an email without downloading a virus, i have a coworker that believes beyond a shadow of a doubt the world is flat.

The Average human is a lot dumber than people on hackernews and reddit seem to realize, shit the people on mturk are likely smarter than the AVERAGE person

There are things Chimps do easily that humans fail at, and vice/versa of course.

There are blind spots, doesn't take away from 'general'.
