The problem with concurrency and parallelism is ownership — mainly that is write access than coherence. I have seen again and again the bad habit of people to bypass well defined set ups of data ownership because they feel they are smarter, it is unnecessary, we will figure it out down the road, and my favourite: it doesn’t solve deadlocks so why use anything as some bug families remain. The issue is not of frameworks or type systems but of companies and people. Engineers know this stuff by training, but either are new and commit hubris or management makes them (or maybe some of them are simply untrained — and somehow never went to a bank (queues)). P.S. For fun instance, I have seen unsafe used to bypass Rust’s type and ownership system to keep track of db snapshots in a “nice setup.” Rust was not wrong.
