Sam Altman doesn't have to write a line of code to make OpenAI successful.
Instead, all he has to do is not intentionally sabotage the efforts of the engineers, via overly doomsday predictions of diamond nanobots or skynet that result in OpenAI not releasing a product because of false claims about "safety".
The problem with OpenAI, and their biggest weakness, has always been that many of the original people there were ideologically captured by what is effectively a doomsday cult.
So all Sam has to do, is not fall into that trap, and instead have the company lead and run by bog standard tech employees, and OpenAI will be able to release great products that will change the world.
He just needs to press the "release" button on all their projects, and OpenAI will be fine.
