For the general programmers/developer, parallelism needs to be 
deeply integrated into the language and it's std library, so that 
it can be 'inferred' (by the compiler/optimiser).

Perhaps a language like D, could adopt @parallelNO to instruct 
the compiler/optimiser to never infer parallelism in the code 
that follows.

The O/S should also has a very important role in inferring 

parallelism has been promoted as the new thing..for a 
very..very...long time now.

I've had 8 cores available on my pc for well over 10 years now. I 
don't think anything running on my pc has the slighest clue that 
they even exist ;-)  (except the o/s).

I expect 'explicitly' coding parallelism will continue to be 
relegated to a niche subset of programmers/developers, due to the 
very considerable knowledge/skillset needed, to 
design/develop/test/debug parallel code.
