Concurrency and Parallelism are worthless jargon

Some people write blog posts on the fine distinctions between the programming jargon of "concurrency" and "parallelism" as if this is very meaningful. But this is all dumb and stupid and inventing a problem out of thin air. What programmers really mean when they say "parallelism" is multicore hardware and what they really mean when they say "concurrency" is multiprocessing (which for nontechies means you can run two different computer programs or processes at the same time.)

Instead, I believe the general community culture of programming is horribly broken and so results in such garbage. I identify three key points that inevitably leads to such garbage as PHP:
