I don’t believe the metaverse will be a browser app; even Decentraland now pushes to a download because it has to do so many real-time operations. That said, I’ve worked with a few of the Haskell OG team (not directly SPJ though) and if you bring in a functional language designer to work on a project you can bet it’ll start with a new language (I’ve worked on two domain specific languages due to this). Some of the constraints right now with this sort of program are CPU/GPU bound, so if we they’re building a new I suspect it’s going to focus on concurrency across threads/GPUs to support the high rendering requirements etc and make it easier to work with networking and C/C++ FFI GPU drivers. This is speculation on my part though :)
