100k is below starting salary in the Bay Area or Seattle. Most senior folks make 300-450k with Staff level engineers making 600-800k.
I used to work at Google too (in Mountain View). Believe it or not I liked working at Google and I also like working at Microsoft.
I don't need to chase top tier compensation. I just do things I enjoy where I'm learning and my career can progress. Right now I'm mostly writing in Go working on an OSS project managed by the Cloud Native Compute Foundation.
As an aside, early retirement is not a goal of mine.
