But then what purpose would it serve? The last 30 years has brought no lack of new languages, not to mention evolution of older languages. Just use one of them.
The purpose of creating yet another language with Go was to break from what everyone else was doing, to see if a "simple" language would stop developers from playing with fun language toys all day to instead focus on actual engineering.
Arguably it was successful in that.
The purpose was to get rid of C++ compile times and replace C++ with Go, failing that, they decided to pivot the story.

They also got lucky with Docker and Kubernetes, pivoting from Python and Java respectively into Go.
