I'm not sure how it's relevant that you worked in a donut shop? Surely you're aware that isn't the peak of over-achievement at the age of 20? God, watch the Olympics if you want to see a bunch of very determined young people. Or go to an Open Source conference. Or, as it were, YC. Sam was only slightly younger than normal there. Some 20 year olds have accomplished a lot.
You seem to really want to create a villain out of the situation, which is kind of weird. Mentors and investors are usually older, and 20 years isn't rare. That's hardly Silicon Valley specific.
You also repeated the false thing about him getting a stake in Stripe as a teenager again. Again, Stripe came into existence when Sam was 25. There's just no version of that story that works. I don't know about Sam's Stripe investment, but at that point he was already around YC a lot, even though Loopt was still going. He probably just got in with other angel investors. But at that point he was in his mid-20s and running a Sequoia-backed company, so that's not especially weird.
(There's genuine stuff to be critical of in the trajectory of OpenAI, but this seems like a really weird spot to latch onto.)
