So what? Why does it matter if his parents have money and are able to help him with knowledge? It is still amazing that the universe produced this kid who could do it.
Suppose it would be possible while poor, and only his high IQ enabled him to do it. Then it would still be his luck for having parents with genes that produced high IQ in their kids. So it would still be "privilege".
What's more, his parents don't just happen to be all that, they presumably worked for it too, including looking for a suitable partner to have kids with.
It might even inspire the one or other person to try to earn more money to enable their kids to do great things that require a bit of money.
Or what is the reasoning behind privilege theory? If you go back in the ancestry of this guy, eventually you'll find some colonialist exploiting slaves, and if you go back in the ancestry of poor kids who don't create chips in their garage, eventually you'll find an exploited human who never had a chance to earn money?
Not even mentioning that creating chips in one's garage is not the only kind of achievement there is. And some poor kids do in fact succeed in life.
Steve Wozniak also was lucky to have a da who was a cutting edge engineer. So I guess that makes Wozniak owe all his money to society now, because he had such an unfair advantage.
