I mean I’m being honest I’m a little bit in love with Rust haha, so I can recommend learning that if you haven’t yet, it has teached me the most of how to design nice programs/libs (in an efficient manner) and generally just feels nice to write. And a very relevant side-effect: it seems like it has a rapid growth also on the job-market. I really feel that growth in terms of improving library quality and tooling (rust-analyzer is I think really the best language server by now), not the least seeing ever more often something like this: https://opensource.googleblog.com/2023/06/rust-fact-vs-fiction-5-insights-from-googles-rust-journey-2022.html)
