There's a bit of a renaissance here in Rust, or perhaps this is just my bias. Many people are drawn to the lack of a garbage collector and efficiency of the runtime code. Lots of packages optimize algorithms that are unlikely to be strictly necessary for the task at hand.

I think it will remain niche to care deeply about these things but they aren't forgotten. In my late 30s and finding this type of thing more and more fascinating despite working for companies building criminally inefficient software using Ruby and Python and dozens of microservices.
