Yes, and no.

Two decades ago it was a challenge to get people to see that what they were doing was preventing horizontal scaling. Today horizontal scaling is table stakes and people don't even always register that they are doing it. It's just how we do things, no thoughts.

PIM requires problems to be decomposed into horizontal scaling problems. Then what you should do with PIM is take a problem that used to be solved by 2 racks of computers and squeeze it down to less than half a rack by stuffing a bunch of these into a single box to do 8-10x as much work per box (and double the cluster size to offset Jevons' Paradox because it's so cheap now that you'll do 2x as much of it)
