I actually think Go's simplicity is a weakness because it will only get you so far. Take web development for example, all the tutorials show json.Unmarshall, but this one stackoverflow post says I should use json.Decode. Oh shoot now I'm having all sorts of problems because I don't really understand json.Decode.

Furthermore I think most people reach for Golang in the beginning because they want performance. However I've found it incredibly easy to write unperformant Go.

I think Golang will ultimately be a very important stepping stone in language development in terms of concurrency, type systems, standard libraries, deployability, and many other categories. I think a lot of important programs will be written in it. And ultimately I look forward to how future languages draw from it.
