You're absolutely right, I was keeping it simple to stay out of SJ fanboy derailments.

Key is he was not a one-trick pony. Real data to prove it.

Right now I'd put Bezos in that category with an n=2 (ecommerce, AWS).

To show a counterexample, Brin/Page have an n=1 - ads. Rest is cool tech, but not significant business and yes, I am adding Youtube into the ads business idea.

Same with Zuckerberg, both Instagram and WhatsApp were about adding eyeballs to the same business model - super ideas, but additive. If Facebook Workplace takes off as a paid-for business, he will have n=2.
