Good enough is not really good enough.
I've seen a lot of "really cool unique designs" that are obviously just a digested regurgitation of amalgamated corporate slop. Anyone wanting an actual unique design language needs to hire actual designers.
Those designers may use AI tools but the tooling isn't to where they can be completely replaced. I challenge anyone to show me an e2e LLM design toolkit that can actually replace a designer, not just one shotted "wow that looks so cool" character designs.
