Define hack.
Define famous.
The weird French fields medal guy with the spider was running for president, he's quite wide known and - while weird - not to be called a hack.
In fact I don't know a good definition of "hack" to make many scientists hacks. It's just that some people who chose the sciences like attention like any other person in the world and so when they get a chance, like Tyson, they get fucking annoying and their plebbiness. shines through. I think everybody is retarded in their own way.
