Has Golang fizzled? It has struck me as too primitive, but basically on the right track.
My biggest issue with Golang by far is the close tie to Google. They are not our friendly innovator, time and time again they make decisions that will help them earn more ad money, and nothing else. And they have a lobg history of releasing something and then never fix the issues with it, and then more or less abandon it.
Other than that there are afaik some other issues with go, I'm not an expert but from what I hear the GC is quite aggressive and you can't tell it to run when you want. Doing something time sensitive? Well, bad luck. GC time!
I think the last two seasons were very much hit or miss. Some really good eps but also some really awful ones.
