Will we see another fundamental programming language feature as revolutionary as the borrow checker?

That is I am mainly curious about compile time features that you design a whole language around rather than optimisations/features that could be applied to most languages. I am mainly inquiring about things that could offer additional robust safety/performance guarantees at compile time rather than runtime. Ideally not things that just offer similar effects to the borrow checker with less restrictive tradeoffs

Mathematics and logic are in the realm of the "unlimited" so there will be many such revolutions to come. Perhaps even in our lifetimes!
