But why?

Little bored. Not learning as much as I used to. I’ve been doing the same thing too long and need a change. It’d be nice to primarily work in Go rather than work on Go.

When I first joined Google it was a chaotic first couple years while I learned Google’s internal codebase, build system, a bunch of new languages, Borg, Bigtable, etc. Then I joined Android it was fun/learning chaos again. Go was the same when I joined and it was a new, fast-moving experiment. Now Go is very popular, stable…
