Not going past the end of a string or array is C 101 and yet buffer overruns abound. Rust's memory model doesn't do anything you shouldn't already be doing in C, but it provides real value because in practice people are demonstrably bad at doing those things. So would a SQL variant or successor that made these "beginner" mistakes a lot harder to make.

No one is going to adopt some new “sql, but it solves a dumb problem you’ve already solved!” variant to solve a dumb problem they’ve already solved, no matter how many beginners seem to be writing accounting software with no knowledge of all the ways that problem has been solved.
