I feel like this might have more to do with modern social media and celebrity culture, especially Twitter culture, than with Tyson himself. It's toxic. It's really hard to move in that realm with out adopting some of its sensibilities and tone. In Tyson's defense, the new Cosmos was damn near perfect and had none of the elitism that I detected. Just a love of knowledge and history.
Tyson is intellectually underwhelming and doesn't seem to understand the limitations of his own knowledge. He's made his fame for speaking with the mannerisms of a preacher; and for remaking (in science a necessity) the Carl Sagan classic. He's already being forgotten by mainstream culture, which is not worse for it.
I disagree. Out of all pop-sci educators there's three that just about everyone who likes science knows: NDT, Bill Nye, and Carl Sagan.
