So you think Go is a better language because companies that use Go are more likely to be successful because... Go is a better language? That's just circular reasoning. Do you have any numbers or experience here?
(In my limited experience I've seen a 100% success rate for companies that use Haskell and a 0% success rate for companies that use Go, though as you can imagine I don't have a statistically valid sample size)
Right, there is no good data at all suggesting that languages like Haskell are better for teams. Yet we are constantly served peoples overly confident opinions that they are.
As someone with experience in both languages I disagree. Try parsing json in both languages and you'll see a difference. Composing functions that use channels simply isn't possible in Go (please prove me wrong).
Go gives you kind of safe concurrency, Haskell gives you actual safe concurrency.
