Parallelism without concurrency is useless, and concurrency without parallelism is usually cooperative and does not have the same challenges. So in essence, the title is correct.
preemptive concurrency is almost as old as interactive computers. Until fairly recently, most computers were single core, but you wouldn't have wanted to use a cooperatively scheduled OS [1], especially on a multiuser machine.
[1] yes, in the '80s some popular microcomputer OSs were single threaded (DOS) or cooperatively scheduled (classic macos and 16bit windows), but even then preemptive OSs were available (amigados).
SIMD is parallelism without concurrency.
