> He might be a brilliant programmer and problem solver, but that incident left a very sour "Grifter" vibes.
Your algorithm for "who is a grifter" is buggy. You can tell someone is not a grifter based on what code they ship, not what words they say ("Cypherpunks write code" being the mantra).
Failure doesn't prove someone is a grifter, btw. Not acknowledging failure is what makes one a grifter. A grifter would continue to draw a Twitter salary without actually fixing anything and were many such cases before Musk took over! Instead, Hotz quit upon realizing that he couldn't do what he said and publicly acknowledged that he couldn't fix Twitter search.
This is also why his companies/projects have bounties instead of "internships". Their code is open source and actually writing code is a simple filter that eliminates people who don't write code but are good at _saying_ that they will. By not even guaranteeing a paid internship in exchange for a pull request, he ensures a contributor's incentives are aligned with improving the technology as opposed to gaming a hiring process. And he pays cash for bounties so you can accurately evaluate whether it's worth your time to contribute.
In other words, he learned from his failure at Twitter that if Twitter's code had been open he would have been able to make an accurate assessment of whether he could fix it by actually submitting a PR!
