Musk is a good project manager if you think that crash or crash through is a good project management methodology. And Telsa and SpaceX (Which is supported by defence industry) are very different in their offerings than twitter.....
So he lead first new major US car company in a century and started the first viable private rocket company in 50 years, but you’re concerned that he won’t be able to figure out how to make Twitter profitable?
People want cars, defence wants rockets. People use twitter, but in the list of things that are required in the future. A terse environment for people to shitpost each other may not be essential.
The skills to run SpaceX and Tesla transfer to running Twitter a lot more than basketball to cooking. For one thing, they all (leading SpaceX, Tesla and Twitter) have running a large business in common.
