First we've seen a continual drop in the number of Seattle based engineers who are willing to relocate to the Bay Area. It's dropped by over half since the start of the year and it's the first sustained drop we've seen since starting Triplebyte in 2015.
Second, we've seen an increasing number of Bay Area engineers interested in moving to Los Angeles even as the average software engineer salaries in the Bay Area continue to grow.
As someone who moved halfway across the world and left family/friends to move to the Bay Area, it makes me sad to see how it's becoming increasingly difficult for people to move here. I believe this is the biggest threat to Silicon Valley's dominance as the center of the technology industry.
