Yeah why is "the algorithm" the thing we do in our head to mimick a 1970s computer and not what really happens on hardware.
Use the royal "we" with caution, please.
P.S. in case it wasn't obvious, this isn't one of those "nyeh nyeh well you must be dumb because you don't cogitate in ways reminiscent of modern computing hardware" comments so much as a "you would not believe how simple-as-in-basic-as-in-limited some of us really cogitate while leveraging external systems to suggest otherwise ".
