The younger generations of coders are indeed more susceptible to hype, but if you go around dismissing things that are hyped, you're going to miss out on a lot of good things. I've got 15+ years of Java experience, and I think Go is a nice language and has some real strengths. From what I can see, the primary difference with Java isn't the build system or the binaries, it's the decision to strongly favor simplicity and readability over expressiveness. The payoff for this is that you can jump into any Go codebase and figure out what's going on fairly quickly. You don't need to pull down the source, fire up an IDE and start drawing object diagrams, you can figure out what it's doing by skimming the source on Github. I find this very useful.
I'm dismissing it because it's dumb, not because it's hyped. Rust also has a lot of hype and is a much better language. You don't have to like Clojure or Algol or APL or Haskell but these languages at least have some intellectual merit. Golang on the other hand... I'm at a loss for words for how deliberately bad it is.
This is really some shameful discourse. It's somehow worse than the usual fare of "nobody but beginners/idiots would choose Javascript if they had other options."
Google is a patch work family where the siblings constantly fight each other for their parents' favor. All the teams are competing for promotions and money that you get through "impact". Go and Dart are just like all the other Google products that get released with much fanfare and then quickly forgotten once their creator's no longer need them for their next brag sheet.
