I'm amazed that PG can't see his own arguments clearly lead to massive social harms.

Facebook once existed as "How is a company going to make money from undergrads stalking one another online?" but that company didn't make it big. It was only when it turned into an addictive harmful website that thrives by massively raising the suicide rate of kids, that's when they made it big!

AirBnb once existed as "Who's going to pay to sleep on an airbed on someone's floor?" but they didn't make a billion dollars doing that. It wasn't until it turned into a DYI hotel that displaces local resident, concentrates wealth, and makes housing unaffordable. That's when it made serious money.

So yes, nominally, each of these startups sounds good. But many of them turn into rent seeking, closed ecosystems, that prey on users.

Correct. I wish PG would do that. Instead of telling this idealized fantasy.
