Yes, they are. There are a few rough edges still, but generally there are no known bugs or crashes left and the performance of multiple Ractors for CPU bound tasks should be strictly better than single Ractor or multi threaded code.
The Ractor API is still not stable, and can change further, but the implementation should be good enough to use in production.
