In an ideal world, nothing. I would hope that the only benefit to<br>
those coding in Erlang is that maintenance would become more of a sure<br>
thing for the OTP maintainers and that, in particular, new feature<br>
implementation and performance improvements would become more obvious<br>
and safer to implement over time. Those benefits would be beneficial<br>
only indirectly.<br>
<br>
That said... I really can't imagine such a large, old, well documented,<br>
well explored runtime known to such a large team would be rewritten to<br>
a new language. I can imagine that some of us (probably including some<br>
of the OTP team itself) would enjoy working on a rewrite in Rust that<br>
is an alternative to, but not a replacement for, the current runtime.<br>
<br>
Competing runtimes occasionally expose hidden benefits. But a blanket<br>
replacement would be a massive, end-of-Netscape type upheaval. It is<br>
not as though Erlang is implemented in an obfuscated style of C++ that<br>
suffers from fundamental structure and human incompatability issues.<br><br></blockquote><div><br></div><div>Large C projects can potentially be rewritten in Rust gradually.
