I don't know. I've worked in three different languages for years on end, and they all have different pain points. C++ is too complicated, and generics are part of that complexity. Java has an ok basic language, but the ecosystem is weird and fad-prone, jumping from beans to patterns to annotations to injection, searching for the One True Way. Go is a little too simple, which sometimes leads to rewriting fairly straightforward stuff that a few clever general mechanisms would let us write once.

This experience makes me suspect that there will always be some pain point with the language. We'll never be happy; that's impossible. The only thing we can do is choose what type of unhappiness we are willing to live with.

The thing I love about Go is its fundamental clarity. It's very upfront and literal. I find it easy to understand what is happening in any particular bit of code. And I suspect that whatever complexities we add would compromise this clarity in the name of brevity. I'd spend less time being bored, and more time being puzzled or incredulous. And fundamentally, I'd rather be bored.
