I agree with most things you say. This is why most DBs are written in C relatives or descendants: C++, Rust, or just good old C. And Java dominates in the server-side business logic domain.

But boy it's cumbersome in anything other than those long running jit-friendly server-side processes..!

PS for IO-heavy purposes almost any mem-managed language would do. The real code running there is OS figuring out hardware and physical reality.
