I wonder if the future will be massively parallel, when CUDA and opencl came out I thought that future processors would have more and more core, so if you follow Moore's law, CPUs would see their core count double each 6 months. The problem is that GPU don't have error correcting codes, so you cannot really run application code on a GPU.
The problem with parallelism is that C-like language don't fit well, only functional languages do. If you want to use multi-threading you have to forget about state and only work with input/output paradigms. For OSes it might mean a deep re-design, but I don't really know.
A possible design would be a small but very fast CPU that only takes care or scheduling and task control, and another chip with many cores that deal with payloads and user software.
AMD had some kind of hybrid chip that planned to do both graphics and task, but it was thrown away.
Going parallel would require to change both hardware and software, and by software I mean stateless.
