My two cents is that I currently find Elixir and Julia to combine productivity and all the goodness from functional programming really well. Not sure what sort of backlash they'll get if they go more mainstream in the future (which I believe they will). I don't think it's totally hype since I also tried my hands on Rust a lot but I really struggled and eventually disliked it a lot. I couldn't seem to implement any complex structure without resorting to unsafe code. Maybe I'm just a shit low-level programmer in terms of thinking about ownership though.

Complex data structures often need unsafe; writing them isn’t a good way to learn Rust. Most already have implementations you can just use, so it’s not something most rust programmers do often.
