See you don't know which languages I mean.

I never said such thing about Modula-3, but I do believe indeed that Rust doesn't solve the concurrency problem when accessing external resources in distributed computing.

It is nice it has an answer for data concurrency for internal in-memory data structures, that is a tiny slice of solving distributed computing access patterns.

Like those languages that you "know", Rust's place is being specialized on deployments where no form of automatic memory management is allowed.
