Yes, concurrency on a single core CPU is simply not possible. That's why multitasking OS's didn't exist until multicore CPUs became a thing.
If only these "Gophers" knew anything about computing history!

So before 2001 your OS didn't have a scheduler and was incapable of handling more than one process at the same time? The user interface was simply hanging when you told your CPU to do something?
That was the point I was attempting to get across. Single core computers multitask fine, which proves that concurrency is not the same thing as parallelism.
Even in modern times, we have something like the first generation raspberry pi zero, it has a single ARM core, and it multitasks fine.
