What are your opinions on the future of back-end web development? Is the Java ecosystem going to wither away as more modern and better solutions are emerging and maturing?
If so, which language/framework and/or programming paradigm do you think will become the new dominant player and how soon?
Personally I would love to see Rust becoming a new standard, it's a pleasure to write and has a rapidly growing ecosystem, I don't think it's far away from overtaking Java. The biggest hurdle imo is big corporations taking a pretty big risk by choosing a relatively new language that's harder to learn compared to what has been the standard for decades.
Playing it safe means you minimize surprises and have a very large amount of people that are already experts in the language.
Taking the risk will definitely improve a lot of things given that you find enough people that know or are willing to learn Rust, but it also means that you're trading off Java flaws with Rust flaws. That's the case however with every big change, and Java flaws are a good enough reason to make a big change.
I’m surprised no one has mentioned golang. We have the usual dichotomy of java and rust but there’s a very very good option for those who are worried about rust adoption.
I vastly prefer writing rust code but go on its own gets you very very similar performance at the cost of developer experience. I think sum types are the #1 requested feature so once that comes I’ll be a much happier boy.
I have not done much GoLang development, but I am working on automating some dependency updates for our kubernetes operator. The language may be good, but the ecosystem still feels immature.
Too many key libraries are on version 0.X with an unstable API. Yes, semantic versioning does say that you can have breaking changes in minor (and patch) releases as long as the major version is still 0, but that should be for pre-release libraries, not libraries ment for production use.
Sounds like my rust experience but then again it'd be non-existing for some of them.
