Probably in the "pearls before swine" sense. Long-time natives just don't appreciate how much the influx of tech folks is improving things, nor how few cities would love to have such a "problem".
Thats because the long time natives don't view them as improvements. They view them as outsiders coming in and disrupting their communities eventually driving them (the natives) out.
The general consensus in most parts of the Bay Area is that people want things to stay the same as it was the day they arrived.
