> 10 engineers can make a billion dollar company
Not really. It's possible they could, but in practice they cannot. Creating a billion dollar company requires a good idea, good timing, and a lot of luck, the engineers are the least important part.
I don’t see anything in your argument that supports your thesis tbh, if anything, it supports the opposite
More than that it takes things like the right social connections, strong marketing, insight into customer demand, infrastructure spend, etc. You can't normally just convert engineering effort into profit in the way implied.
