Every language that actually gets movement is criticized and go is hyped :).
I love Go ;D still it's hyped and every hyped language polarizes because people get the "u should use go for that" everywhere and you try it before you understand why and where you need it.
It's like the react framework/lib ;D ... imagine how many devs were pissed after they realized they had to build a routing system ? I had loads of them ;D ....
If you don't understand a language / framework / concept and what the advantages or disadvantages of it are .... you probably will misuse it and be pissed or you are pissed because you understand what you need.
