There are a lot of things tech doesn't do right. But tech, in this context, is just a growth industry. There will be another growth industry in 30-50 years, and the exact same pressures will happen again. Will these cities be capable of supporting that industry? Or do they want to remain small towns for their existing population forever? Or, worse, do they want to treat tech as some sort of special case, so they can have entire abandoned neighborhoods full of overbuilt property just for Google because they thought there will never be another Google and they have to do special things for Google in particular?

NYC at least decided to take the first route decades ago, and has survived lots of industries moving in and out.
