We're already past the point of getting our hackles raised when we suspect something is AI written. Everything is or soon will be AI written.
So I don't think it's that useful to blame bad product design on AI.
Bad product design is just bad product design. Bad writing is just bad writing. Bad graphic design is just bad graphic design.
The industry needs to get over this hump of pretending we're not all going to adopt AI for every imaginable thing. The cat's out of the bag, for better or for worse.
