That's wonderful how you tied those threads together to describe Go's philosophical origins. I'm having a great time exploring the links. And the parallel with NeXTSTEP is fascinating too, I've been interested in that part of software history since learning that Tim Berners-Lee created WorldWideWeb.app on the NeXTcube.
Not just philosphical; I've read somewhere that the first Go releases in order to bootstrap themselves they bundled the plan9 forked/simplified C compilers inside. Later releases are written in Go themselves.
There is no philosophical or technical continuity. Go is really not the continuation of anything from Bell labs, not the philosophy, not the technologies, and especially not its purposes.
Go was created at Google, for Google, by Google employees. They looked at how Google was using C++ at that time, sat down, and created a new language that would suit that task more. Here's an article of what and how by Rob Pike https://commandcenter.blogspot.com/2012/06/less-is-exponenti...
It's as much of a Google project as anything can be. "C++ is a katamari ball of programming trends and half baked ideas. I get why google built golang, as they were already pretty strict about what parts of the c++ sediments you were allowed to use." is entirely correct regarding history.
