Re (3): asyncio does not give you a boost for CPU bound tasks. It's a single-threaded, cooperative multi-tasking system that can (if you're IO bound) give you a performance boost.
Ehhh I mean you're not wrong, but I wouldn't say you're fully right either.
You can absolutely send stuff to a thread pool executor or process pool executor and then never await the returned value/never have it "return until interrupted, but the issues with shared memory (or really, the lack thereof in comparison to ex C) are still present to my understanding.
Then again, I mean you can always spin up a sqllite server or something on the same machine, but that's stupid heavy and more of a workaround than a solution. Super excited for nogil.
It was clear from the context that he meant concurrently running not concurrently in progress. I wish nerds would give up on this parallelism/concurrency pedantry or at least choose some new nomenclature that didn't conflict so massively with the English meaning of "concurrent".
I mean it's not even right. Most parallel/concurrent pedants would consider multithreaded code to be "parallel" even if it is running on a single core.
I think the best thing is to talk about threads, because then you can distinguish e.g. OS threads and hardware threads.

If you're using these as technical terms which have specific technical definitions, then concurrency and parallelism are distinct but related concepts, and parallel computing means executing code simultaneously on separate execution units, not time sliced on a single core. So yes I am actually right about this. Parallel computing is defined this way in CS and it's not a matter of opinion.

Hm, I think running on a single core is the exact definition of what the "pedants" say is not parallel. If all you have is one core then you can't achieve parallelism under their definition.
I think the terminology is pretty well established now. But I do agree with you that it's a bad choice of words and that it's annoying, intelligent even, for people to pick a particular unintuitive definition and then go around brow-beating people for not using/understanding their definition.
