Some people around here think Elon Musk is good at public speaking. I wouldn't pay too much attention to the opinions of nerds on topics like charisma.

My point was just anything he did with open source is orthogonal to charima, even if you also think he isn't charismatic; I havent gotten any charasmatic vibes off him though he does seem to have an intense stare at interviewers that doesnt really come off as charasmatic but maybe kind of Elizabeth Holmes-y and she obviously was very convincing to people and effective at manipulation. To me Holmes didn't seem charismatic either but there was definitely something that convinced other people.
