He’s a tech guy who got super lucky and became filthy rich.
Not even that…
He was (at best) an average coder decades ago who used family money to buy lots of startups and a few made a lot of money.
He was a gambler, not a businessman. It’s just when you start out wealthy you can keep buying lottery tickets till you win. It doesn’t even mean he was good at picking lottery numbers, he could just afford to buy more tickets than other people.
