That wasn’t meant to be a snide comment about Erlang in any way. All I meant by the comment about higher-overhead was that the language itself generally has more costs to run, i.e. runtime, memory usage, garbage collector, interpreted, etc, than Rust.

The “process” model of Erlang is about as lightweight as you can get, agreed.

In terms of capabilities of beam across systems, point taken. Though we start stretching some of the understanding of where languages end and runtimes begin... Rust and C make those boundaries a little more clear.
