I don't buy that argument. ICs are massive. Way bigger in terms of number of schematic pages than any PCB. I think the problem is that PCB designers are used to having very "flat" schematics whereas IC designers always have a lot of hierarchy. For example, the madness with the schematic he shows in that video for all of the by pass caps is something you'd never really see in an IC design. The cap would be placed in the schematic hierarchy either right at the voltage regulator or right at the circuit where its needed. But on PCB schematics you see that kind of thing all the time. Part of the problem may be that with an IC you can easily simulate anything. The whole workflow is built around it. For a PCB, outside of using models for standard analog building blocks via spice simulator, it's a lot harder to verify your design.
