IMHO, shared memory parallelism as the norm, means we're still in the dark ages.

Yes, shared memory is useful sometimes, but I don't think it should be the norm. But I've done parallel stuff in lots of languages, most recently Erlang and Rust... Message passing is so much nicer than having threads all mucking about in the same data if you don't need them to. You can write message passing parallel code in Rust, but it's not the norm, and you'll have to do a lot of the plumbing.
