Everyone always says this type of response about everything though. If you like X, you’ll say, “In my experience you can /s/X/Y and all the criticisms of X are even more damning criticisms of Y!”

All I can say is I’ve had radically the opposite experience across many jobs. All the places that used monorepos had horrible cultures, constant CI / CD fire drills and inability to innovate, to such severe degrees that it caused serious business failures.

Companies with polyrepos did not have magical solutions to every problem, they just did not have to deal with whole classes of problems tied to monorepos, particularly on the side of stalled innovation and central IT dictatorships. Meanwhile, polyrepos did not introduce any serious different classes of problems that a monorepo would have solved more easily.
