Importantly, Go is a good evolution of the C idiom
It's pretty rare that anyone can re-invent a full language/support that has some critical mass from the start.
Even Java took several years to be considered a worthy language for business-class apps. Having Ms. Google as the underlying supporter is not bad in the supportive-role sense. And really not bad in the other senses since the dogfood is eaten by everyone.
I'm a big fan of the "C"-class languages vs. the sloppy-indentation style of Python/etc. I also like the strict requirements for dependency management (if you say you're going to use it, you damn well better.)
I'm sure there will be better/different ways of dealing with software development problems. Go is definitely a big step in the right direction.
