I'd expect most things to work and have native versions by next year, with the notable exceptions of virtualization software and package managers like Homebrew.
Virtualization software likely will never be fixed if you expect an x86 guests to work. The hardware obviously cannot natively virtualize x86, nor can Rosetta cannot emulate privileged x86 code. x86 Docker images will also not work.
Homebrew itself will probably be ported to ARM by then. However, there will likely be a long tail of packages that won't have ARM builds for some time.
