I mean, I agree when build times take more than a minute, I don't care about seconds. Have you used languages that take less than a few seconds (in total) to compile?

Also in my experience Crystal compiles simple projects faster than Rust and somewhat comparable to Julia, but much slower than (e.g.) C or Zig, which I think is fine for a language with higher level features. Maybe I haven't done anything big enough with Crystal yet to see the compilation times though?

And of course, I expect it will get better over time, there are things that can be done like parallelization and cached incremental compilation results (like Cargo or Gradle do)
