You're getting downvoted because your post is "middlebrow dismissal" (https://news.ycombinator.com/item?id=5072224) which is also unnecessarily aggressive. It's quite possible for someone to know exactly what you are talking about, and still downvote it.
Regarding the technical points, having low-level mechanisms for fine-grained synchronization between threads (such as these) does not prevent you from also providing high-level mechanisms for parallelism and concurrency. In fact, it enables others to develop such abstractions in that language in question, without relying on the language itself to provide them.
