Re: A possible explanation for sudden behaviour change.
Musk has been questioning the severity of the pandamic and the responses to it since the beginning, so again, it's not new enough to be attributable to new fatherhood - though I doubt it's helped.
Didn't he allude to his mental health in 2019, something about having taken too much on? I can't remember now.
As a businessman, his approach to the factory could perhaps be smarter - it's not good PR. Good PR would have been to go above and beyond reasonable precautions for staff - working distances, protective equipment etc - and then point it and request it be allowed to reopen in consultation with his staff.
Anyway, for a bit more context of his current state than can be gleaned from Tweets, he was on the Seth Rogan podcast last week.
