Rust should help with the stability issues that plagued the 80s/90s before fully enforced memory protection. Now I wonder if MMU really brings other benefits. In my latest workstation, I do not use virtual memory to use the disk as extra memory for my running software, i use compressed memory as a disk cache. 30 years of progress has changed the requirements and usecases. Maybe the MMU will survive in a different form that would require a new name. I read the 4k virtual memory pages and TLB caches are becoming a performance bottleneck so this needs to be redesigned anyway.
