I suppose I'll need to check it out, I am not on Twitter so don't frequent it.

At the same time... If twitter existed back then, how would the famed scientists and communicators come out? Einstein, Feynman, Asimov, Clarke have all had pretty damming (defined at minimum as "unacceptable by modern cultural standards") behaviour come to light. Respected scientists and philosophers of 70s who are still alive have similarly gotten themselves into serious hot water on social media more recently.

Never meet your heroes and all that...

NGT posts some pretty cringe science takes too, though. The kind of stuff you would expect someone in his position to put even the slightest bit of research before speaking.
