I didn't say he's failing at everything - SpaceX certainly seems a huge success. Telsa had been doing well, although sales are now declining fast, and the Cybertruck has been a failure. He massively overpaid for Twitter, ruined the site, then got X.ai to bail him out. X.ai seems like a failure - evidentially not enough demand to utilize the data center he built for it, and when have you seen anyone say they use Grok for anything ?

And now SpaceX investors are going to be left as the bag holders for X.ai/Twitter.
