The SF advantage is so incredibly ephemeral. Everybody wants to go there, because everybody else is there.

If that is all there is to it -- and it is -- this process can very easily go into reverse mode. SF is insanely expensive. You do not need any part of SF to write good software. It only makes your software more expensive.

Some day -- that could take quite a bit of time though -- SF will crash and burn, simply because there is no reason why it wouldn't.

It's been ephemeral for some 60 years now.

Some ephemeralities are more durable than others. Not that they cannot change.
