Some things Musk claimed have happened, others have not. For example, he promised that they would release a satellite Internet platform that was better than most of the others, and they did.
On the other hand, he promised that Grok 3 would be massively better than ChatGPT, and it turned out to be comparable at best.
When you make a lot of bold claims, and you have your (or a lot of someone else's) money to help you back up the claims with (clumsy) actions, sometimes your bold claims turn out to be truthy.
Sure, ill sell you this broken clock. Its been shown to know atleast two times a day.
