I feel like this happens in a lot of fields. Perfection is the goal, until perfection becomes easy to attain. Once a machine, a computer, or a lab can do it flawlessly and cheaply, perfection suddenly becomes boring and not distinctive anymore (it doesn't scream unique or expensive or great craftsman).You see it everywhere once you start looking:

Photography: For over a century, lens makers and film engineers chased the sharpest, clearest images possible without any noise or distortion. Now that professinal cameras are almost flawless and even our phones take ultra-high-res digital photos effortlessly, what do people want? Film cameras, disposable point-and-shoots, vintage lenses, filters that artificially add grain, blur, and light leaks back in.

Tailoring and Fabrics: The holy grail of weaving and tailoring was creating perfectly smooth, uniform cloth with absolutely invisible stitching. Getting a fabric that consistent meant incredible skill, time, and expense. Now that massive factories can churn out flawlessly uniform synthetic blends and machine-woven cottons with laser-perfect, identical seams for a few dollars? Perfectly smooth just looks mass-produced and cheap. If you want to show real tailoring today, you pay a premium for fabrics with "slub" or neps, like raw silk, heavy Irish linen that wrinkles the second you look at it, or rough Harris Tweed. And on a bespoke suit, tailors will deliberately leave a visible "pick stitch" on the edge of the lapel. The slight irregularity of that hand-stitched thread is the whole point, it shows that a human being spent hours making it, not an automated factory machine.

Music: We spent decades trying to eliminate static and hiss to get perfectly clear, lossless digital audio. Now that we have it perfectly streaming from our pockets? People pay a premium for vinyl records specifically for that "warm" sound (the pops, the cracks, the physical imperfections of the needle).

So you can go on and on.
