Python has good co-routine support. In Python 3.5 we have async/await and the concurrent.futures module. For I/O bound tasks like running REST APIs or MapReduce jobs I don't see the GIL being much of a problem; you spend eons waiting to do a few milliseconds of work then wait some more.

I'd agree.

In my experience it's easier to explain a solution to a fundamental problem than to an abstract one. Channels, futures, promises... all very abstract concepts; useful to the cognoscenti but none are satisfactory at solving the fundamental problem of parallel execution. Hence everyone in their camps about which is right for which tasks.

So even with channels parallel programming is still difficult. You just have the added burden of a different, unique abstraction. Every language ecosystem either has their own community-adopted one or a plethora of them.

I think I'll reserve, "dead simple," for when we have a universal language of parallel execution. Until then... we don't know how to compute!
