I think the name of this Ruby feature is unfortunate, as it doesn't really communicate what it's about, and promises something it can't really deliver.

Using ractors as actors in the Erlang genserver sense is not really feasible. They're too heavy, you're not going to start up thousands of them.

Ractors are an interesting feature, with maybe some specific applications related to data processing, but they're still highly experimental and have yet to be understood and embraced by the Ruby community.
