All the startups are moving to other markets. The problem long term is that all these startups provide the training for people that eventually join those other companies. Eventually unicorns will show up in other markets that don't have the insanity of the Bay Area. When that happens these companies won't be able to attract talent and risk becoming a shadow of their former selves along with the city.

At one time Armonk, NY and Maynard, MA were the center of tech too.

It's will be a long slow death by a thousand cuts.
