You make it sound like the only point of threads is to take advantage of
parallelism when the program is running on a multiprocessor machine. A lot of
people use threads for reasons that have nothing to do with (objective notions
of) performance, for example in GUI programming. By your logic, there
would seem to be no point in emulating concurrency on a sequential machine at
all.
