The "somewhere" is, of course, in one of the previous steps. I agree with him that there are vanishingly few legitimate[1] use cases where a queueing system is the right solution.
More, but only ever so slightly, more frequently, a spool is called for, and that can be loosely simulated by a queue.
[1] This excludes situations of ones own making, such as designing a system that requires asynchronous but ordered execution in the first place.
