What important truth do very few people agree with you on?

Great tech opportunities happen only once.

I'm skeptical of a lot of what falls under the rubric of education.... People are on these tracks. They are getting these credentials and it's very unclear how viable they are in many cases.

EVERY MOMENT IN business happens only once. The next Bill Gates will not build an operating system. The next Larry Page or Sergey Brin won’t make a search engine. And the next Mark Zuckerberg won’t create a social network. If you are copying these guys, you aren’t learning from them.

The zero-sum world [the movie The Social Network] portrayed has nothing in common with the Silicon Valley I know, but I suspect it's a pretty accurate portrayal of the dysfunctional relationships that dominate Hollywood.

I think in my twenties I tended to think of all people as sort of more or less alike. In now think that people are really different in all these subtle ways that are very important.

The developing world can just do things that are extensive or horizontal, that basically copy. The developed world needs to do things that are intensive or vertical, where we take our civilization to the next level.
