That I can easily believe. Someone should make a benchmark of how many requests you can serve from a java backend compared to a rust backend that's heavy on IO and network.
Yeah an 8 year old benchmark doesn't mean much, both languages/platforms surely have evolved greatly and I would not surprised that on many meaningful workloads there is some parity.
I never understood the fascination for working with cutting edge languages; to me it just increases the likelihood that you're going to find language errors or library errors and get tied up for ages helping to refine the environment. Plus the relatively small size of the developer community and supporting literature available.
Maybe it's a dog people thing, the sort of people that get into it are the sort of people that want to go home and have a dog with infinite energy bouncing up and down all the time.
I have been actually professionally working with Rust for the last 2 years, and most recently on certified safety systems.
But I'm always thinking that the JVM is a pretty solid platform that has not yet reached its full potential. It gets a bad rap because of the hellhole that enterprise software is. But come on, look at android, look at games like Minecraft. Solid projects, written in large part in Java.
Describing Minecraft as "solid" makes me very scared reading "certified safety systems". Minecraft is the most standard possible example of Java's badness and bloat. It's explicitly what software should strive not to be.
It's a game first and foremost, and it mostly works, quite well, with multiple players. It's a completely different set of requirements from safety software.
And people write mods for it and have had success. If that is not solid what is. For real what's so bad about minecraft, it even runs on a relatively old laptop of mine with 8 gigs of RAM without any lag.
In most safety software you can't even use dynamic memory. Maybe a lot of the software we write in that domain would be considered "bloat" in others, but I don't know what are the constraints that Minecraft faces that drove it to be implemented the way it is. But despite the bloat, they managed to do a lot.

When Minecraft came out, 8G of RAM would be pretty much the highest-end system you can buy. It's really not the flex you think it is.
In terms of the opposite direction from Minecraft in stability is Factorio, which can easily run on a multiplayer server for a gaming group on a potato of a computer and whose high-end multiplayer record is well over 500.
