One use of design is signaling, but not all - successful design is that which fulfills its purpose.

Many designed things do not need to be differentiated and will benefit from a homogenous AI-powered design (internal documentation, local service business communications, etc) in the same way that desktop publishing replaced hand or type-written notes but did not replace professional designers (although it did require them to learn digital tooling).

For designs that do benefit from being differentiated it'll be interesting to see what happens. If anything, AI homogeneity provides more opportunity for talented human designers who can provide "design alpha" beyond whatever trends the LLMs sucked up in their last crawl.
