The languages that get a lot of airtime on HN are the ones the young people will just use by default.

Hotspot is the current choice for high performance programs, but is Rust lower performance in some way or are the only downsides related to its younger age?

It’s perhaps useful look at what languages brand new projects are being started with rather than just looking at what languages large established companies like Netflix are choosing.

Rust is not inherently slower but then again neither are C and C++, but in practice all of those tend to be less efficient than realistic Java systems. Rust is displacing C in contexts where Rust's less than amazing performance are not noticeable in contrast to C's also-not-amazing level of performance. And I also think there is a cognitive bias under which a developer will reach for Rust to supplant a legacy C program, because that developer reflexively dislikes managed language runtimes.

Depends where you are, in startup world definitely yes. Elsewhere, not so much.

Companies couldn't care less about the underlying platform or language, they want reliability, stability and tons of easy to find people who can work with it from Day1. Java delivers all that, and will keep delivering for upcoming decades. Big businesses and big money love this (or hate the least out of IT stacks).
