Python developers often really liked Go and SREs who had to maintain major python projects REALLY liked go
There were IDEs for python, but they weren't at the level of maturity that Java or C++ had. They were dynamically typed and so a little type safety often felt like an improvement rather than a step backwards. The fast compile times were appealing, and the style guide appealed to a group who believed "there's one obvious right way to do it"
We saw a lot of go taking over in that space 10/
Basically: the execs notwithstanding, most engineers didn't see go as a silver bullet but as a nice enough tool in the toolbox, especially for writing, say, command line utilities or simple web servers.
C++ and java devs weren't willing to sacrifice the performance or more sophisticated typing, packaging, etc. They had tools to reduce the complexity they had to deal with and go seemed to shove all of that complexity at them and say "BUT THIS IS A SIMPLER WAY OF DOING IT."
