I personally don't hold Rob to be such a figure. I believe he's quite ignorant when it comes to many important topics in computer science (e.g: he made some comments that make it clear he does not understand parametric polymorphism). I find his work on Go to be a minor variant of Algol69 (and not necessarily an improvement, at that!), throwing away 40 years of real improvements in PLT.
In the final analysis, this is hardly enough to convince me to use the language (as I've never found concurrency difficult in any other language to begin with and there are better ways than go-routines to make it 'easy'); however, I'm probably not in the target audience.
My impression is that Pike is endeavoring to create for his new corporate overlords a language that fungible enterprise developers can be at home in. And, it probably is better than Java.
And, I find Rob Pike completely unimpressive. I would suggest that you find other folks smarter than yourself (and preferably smarter than Rob as well) to blindly follow (if that is your thing).
