It's an indicator, not always the best one though. Your car has probably started every time you tried for years, but if it's suddenly -50c it's a very good bet

It's an indicator, not always the best one though. Your car has probably started every time you tried for years, but if it's suddenly -50c it's a very good bet that it won't this time. In this case it's pretty clear that Musk doesn't have the bandwidth to run another company in the same way as he runs Tesla and SpaceX. You can reach that conclusion any number of ways, counting the number of hours he (claims to/appears to) put in, listening to his own statements on the matter - where he has repeatedly outright said this, observing his relatively hand-off approach to his more recent ventures like neural-link or the boring company. It seems unlikely that his behavior at Tesla or SpaceX is about to change significantly, so it seems unlikely that he'll try and take as active a roll at twitter.
