Because these tech bros like to put forward a fairy tale where they themselves are geniuses and basically carry the company on their shoulders. They maintain this carefully crafted image of being super duper smart and all of the setbacks are just because humanity is catching up with their vision. They use this image to dupe investors into investing huge amounts of money based on ideas that are in principle good, but in reality very much not feasible. A lot of the money is invested purely on the story and image of the one person, where they build each funding round on the previous one, snowballing into something huge.

In reality these people are scam artists, they know how to project their image, how to sweet talk investors and how to lie and commit fraud on a running basis. Sometimes they are caught, like with Elizabeth Holmes, most of the times they are not.

People who actually know their stuff clearly see those tech bros like Altman and Musk are full of shit talking out of their arse. But the general public doesn't know that and believe the lies, but more importantly the investors believe the lies as well.
