Thanks for the list!
I agree that the fundamental thing here is:
> "genius in one thing believes he's a genius in everything"
No disagreement here, and sadly I think this is an unfortunate part of human nature.
Other than that, I'd say the person who wrote that list has a beef with Tyson, there's a mix between honest mistakes and debatable things, a lot of nitpicking (with a dose of cherry-picking), and ultimately this doesn't prove that "most of [Tyson's] takes" are mistaken. I agree that some things he says are dumb (like the cybersecurity tweet you mentioned) but I wouldn't dwell too much on them. "Cosmos", in all of its incarnations, is amazing. Of course, I'm not arguing the script is his, but his delivery and screen presence are solid.
I see Tyson commented on that blog, and some of what he says makes sense (e.g. picking on his colloquial use of "exponential" seems a bit mean spirited, though he could have been more precise; some people misunderstand the spirit of his comments on scifi movies; etc). In general, his replies in that blog to what at some points amounted to personal attacks left me the impression that Tyson knows how to gracefully and politely handle flamebait.
