In my experience, product managers do not spontaneously organize to create successful, billion dollar companies, either.

I'm curious why do you think SpaceX and Tesla are market leaders in their niches? Is Elon the only person who hires product managers?

Tesla's aren't even good cars they are great batteries attached to mediocre cars sold at an unprofitable price rendered profitable only by government handouts.

Testla is market leader in "tesla cars"… which is an odd way to define a market leader.

Spacex, I honestly don't know enough to comment about.

Tesla is the market leader in electric vehicles. Tesla sells more EVs in the US than all the other manufacturers combined.
