Nobody has to actually know the secret of their own success, especially not relative success to equally-secretive near-peers.

Same as with rich person autobiographies: even when they tell you what they think it is, they can't see the path not travelled.

Yup, there's a lot of survivorship bias in those. And humans want to attribute success to some skill somehow. You cannot just have been lucky.

I'm purely talking about the technology - not their business strategy. I actually think their business strategy is blatantly obvious and atrocious.
