You could also be asking about whether it is time to ditch "commodity" hardware (which by the way is not massively parallel).

The answer is, of course, it depends on what your priorities are.

I've seen projects that write OS's from the ground up for a wide variety of reasons (security, correctness, optimization of use case, etc.) But very rarely is it for price reasons.
