Where Rust scores over Go is not so much on the speed but memory usage. As memory is becoming expensive (and likely to stay for sometime), the appeal for Rust increases.

The large disk space usage for Rust is much more solvable than speed-up in Rust compilation as long as crate remains the lowest compilation unit.

Barring this, even for AI based development Golang is much better language. But Rust's long term payoff is too good at this point.
