Too soon. Someday perhaps a Game Developers Conference paper/talk. I was considering one, but live GDC has been cancelled for 2021. My real interest in this is how do we build a big, seamless metaverse that goes fast. I'm far enough along to see that it's possible, but not far enough along that people can use the client.

Rust is good for this sort of thing. It's overkill for most web back end stuff. That's where Go is more useful. Go has all those well-used libraries for web back end tasks. Parallelism in web back ends tends to be about waiting for network events, not juggling heavy compute loads of coordinated disparate tasks. Hence all the interest in "async" for web servers. As I've said before, use the right tool for the job.
