This is only true in the view of connoisseurs. Normal people overwhelmingly prefer AI design (and flattering, grandiose AI slop writing as well). And the naive designs he shows are still made with digital tools. People were probably making the same "hand drawn/painted is better than DTP" argument in the 1980s.
There are a lot of legitimate criticisms of AI design but this isn't one.

Everyone I have talked to universally hates AI design.
