Although still new I'm wondering whether Kotlin could be admitted to the boring technology category given that it was built to dovetail with Java and has first class Spring support?
I’ve found kotlin to be wonderfully boring. There are definitely some sharp knives that get abused though. I’ve met a few people who want to throw OO in the bin and treat kotlin as pure FP to their detriment.
Kind of. I don't think arrow - however good it becomes - can really compete with a language where those primitives (like do notation) come with the compiler.
