I think we will transition to a world where handmade software/design will come at a huge premium (especially as the average person gets more distanced from the actual work required to do so, and the skills become rarer). Just like the wealthy pay for handmade shoes, as opposed to something off the shelf from footlocker, I think companies will revert back to hand crafted UX. These identical center column layout's with a 3x3 feature card grid at the bottom of your landing page are going to get really old fast in a sea of identical design patterns.
To be fair component libraries were already contributing to this degradation in design quality, but LLM s are making it much worse.
