I'm no fan of Musk, but it's hard to argue that SpaceX hasn't been revolutionary, to the point where I question if there's anyone else who could have pulled that off. Moving focus to The Boring Company or Hyperloop feels a little like whataboutism. No one succeeds at everything they do. Musk is in the unique (and lucky, for him) position that he can throw a lot of darts and lose a lot of money, but keep on going even if many of his bets don't work out.

And I don't think the usual "throw shit at the wall until something sticks" thing applies to Musk. Certainly he's had some things that slid to the floor, but he hardly has an "unlimited" supply of darts. And even if his finances were infinite, he still only has 24 hours in a day, and can only focus on a certain number of things. By and large, the things with a lot of his focus do seem to be doing pretty well.

Twitter is clearly a huge blind spot for Musk; while I'm not going to dismiss it out of hand, it does seem like an outlier. Regardless, it's still running, somehow, when I expected it to have been shut down by the middle of last year. While I know people who have stopped using it, I know more people who still use it and get value out of it, regardless of the negatives since Musk bought it.
