Intel Labs did do some work on functional language implementation, including a Haskell compiler (backend): https://github.com/IntelLabs/flrc https://github.com/IntelLabs/flrc I think the focus was on vectorisation rather than task parallelism, though. And it's been abandoned for years. I'm not sure Intel's sustainability is uniquely dependent on parallel programming. In fact, given that Intel processors have the best sequential performance, one could even argue that it's to their advantage that parallel programming remains awkward.
