the ICT sector in particular pulls in people worldwide and has a high flight ratio compared to the normal population, domestic and international. so inside the tech bubble in California, I expect more people interact with people outside their core community, than other places. Compared to Omaha or Austin. Compared to Chicago? maybe not.

but I did mean in-the-wide too; i think since we started down the vaccines as herd immunity game in the 50s and 60s we now have more routine travel and the rate of change here has accellerated. When I was a kid in the 60s few flew, my first flight was at 16 and then no more until 24. Now, I fly 10+ times a year worldwide. Thats only 40 years gap.
