It seems like things might be moving away from managed code somewhat.
Safer native code languages like Rust have been starting to become
more popular in recent years. I think safer native code is a better
approach than Java/.NET-style manged code, since there's no
performance penalty and the runtime is just a library rather than a
more complex VM (which is often written in an unsafe native code
language, leaving more attack surface than a system in which
everything security-critical is written in a safer language). I'm
taking the safer native code approach in the OS that I'm writing (a
Rust-based next-generation Unix-like OS that will somewhat resemble
QNX and Plan 9; <https://gitlab.com/uxrt>).
