JS and Python are my primary languages. I've toyed around with Rust, and it is pretty cool. There were a number of nice moments where I was surprised with how much it felt like I was writing high-level code. However, the overall learning curve is huge, especially if one is mostly used to garbage-collection (like me).
If you are doing web stuff, I'm sure Rust can be used effectively. But it is non-trivial and there are serious tradeoffs (learning curve, lack of ecosystem for web, hiring, etc). Teams would be better off sticking with python or JS for most web projects. Some perf-heavy backend or infra projects could possibly benefit from Rust, but otherwise it doesn't seem like the best choice to me.
It is definitely a cool language that seems to be gaining serious momentum. Could be fun to mess around with.
