Dunno. Rust does some amazing things because it has a linear type
system, which means both that it can be a fully safe language even
though it doesn't have a garbage collector, and that it can allow
sharing of memory without any fear of multiple writers touching the
same block of memory.
I used to think that there hadn't been much progress in computer
science in decades and then I fell down the rabbit hole of modern
type theory. The evolution of type systems over the last few decades
has changed the game in a lot of ways. Most people aren't aware of
the progress that has been made, which is a shame.

You're not mentioning things like linear types, effect systems, etc.
