TL;DR: People be dumb.
Is Bill Nye’s ego not at least as large, though?
(I feel like I should point out that I don’t think either of them are wrong for having a bit of an ego. It’s really hard to be right all the time and surrounded by a sea of idiots without turning into an exasperated jerk – frankly, I think they should both be commended for resisting assholery as well as they do.)
I honestly barely pay attention to BIll Nye because I used to watch him on Almost Live, so it’s basically impossible for me to take him seriously, so you’re asking the wrong person.
Admittedly, I never watched Bill Nye Saves the World, so I don’t know firsthand how egotistical (or otherwise) he was. But still, that title alone says something…
I did watch the obscure Planet Green show Living with Ed, however, in which Bill Nye was portrayed as the rival/antagonist and kind of an asshole. Who knows how much that was being played up for the camera, though.
