Yes.  Parallelism certainly deserves attention, and I believe
"amateurs" are likely to help in the breakthroughs to come.  I
further suspect, though, that they'll be amateurs who benefit
from knowledge of existing research into the range of documented
concurrency concepts, including CSPs, tasks, guarded methods, 
microthreads, weightless threads, chords, co-routines, and so on.
