I question the relevance of newer Java versions. Established codebases don't like to upgrade and new codebases are likely to use trendier languages.

I sorely miss some kind of functional streams api in Go when switching between Go and Java. for-loops make the equivalent code absolutely awe full, plus it’s not automatically parallelizable by replacing .stream() with .parallelStream(). IIRC, some Go luminary decided map, apply filter etc. we’re no good, so I hold little hope of something like Java streams API in the future.

Maybe someone can recommend a third party library.

> Java is far more a productive language

Since when is productivity a priority for most developers? Seems like 2nd or 3rd fiddle based on HN sentiment these days.

Java (and C# and C++) have become kitchen sink sink languages. Everything is just thrown in. That makes it less productive for me. I've decided I don't want to carry around that much in my head all the time in order to read somebody else's code. I switch languages a lot these days.

Go is getting generics in (hopefully) in a few months. Some features are missing but most don't cause much pain and can be either simulated or worked around. Error handling is its biggest failure, but outside of that I find is at least as productive as other compiled languages in the same space.
