If the latest startups couldn't raise new funds (because of investor panic), then suddenly the market is flooded with developers, do salaries, real estate, etc, go down?
Is the startup economy entirely reliant on outside money? (Especially outside of SV money - money like pension funds and other institutional investors)
Or would the Googles and Facebooks of the world - huge profitable companies that they are - absorb the ones that failed, the downturn would be modest, and soon some of those developers would be right back out there starting new things?
I'm inclined to believe the latter.
People decry a bubble for other reasons than valuations, like San Francisco real estate and how high dev salaries are getting. Companies that don't have any revenue but can still raise lots of money.
I do wonder how high dev salaries can go - I think it is tied to how much value a developer can fundamentally produce. It may well be far higher than the current average salary (perhaps multiples of it), so I don't see anything wrong with that.
But you could also say developers are themselves in a bubble, and that the proliferation of app academies and their like will soon catch up with the demand.
