What the author describes is an US and in particular a Silicon Valley attribute. That of a concentration of smart technical people in their own bubble in a nice climate, outside of a wider community.

It's self selection filtering, it's team belonging and humans in groups. It's earnestness, it's bright eyed optimism.

It's not socially awareness, it's not a healthy cynicism. It's not cosmopolitan. It's isolation.

It's why the largest pure technical efforts and successes come from SV and why more socially concious and digital humanities and world humanitarian technical efforts occur elsewhere in the world.
