You seem to be interpreting the statements as technical comparisons of the languages, but ch4s3 was (by my read) commenting on the overall ability of a programmer to jump from one language to another.
That is: they aren't similar languages on a technical level, but if you know Rust, you should be able to make the jump to Gleam pretty quickly.
