A comment on the YouTube video makes a good point that we already have a better word for the concept of dealing with multiple things at once: multitasking. Using a word that literally means “things happening at the same time” just adds to the confusion, since people already have a difficult time understanding the distinction between multitasking and concurrency.
I will typically use the terms asynchronous and parallel when discussing the concepts, but I hadn’t thought about using multitasking until I saw that comment. I mean, even C# calls them “tasks”.
