That right there, is the whole truth. Not only do they not use it, they don't buy it to begin with. What sells and what people like are not the same as what they need or think they need.
Case in point. I developed a process, software and hardware, to take an ordinary photo and turn it into a 3D carving in the early 2000s. There were CNC programs that could do it with a lot of human touch-up, mesh manipulation, and machine coding, but mine went pretty seamlessly from photo to 'send it to the machine'.
Everybody, everybody is not just family and friends, loved it when they saw the photo and sample maple hardwood output side-by-side. People made statements like, 'I would pay an arm and a leg to have a door carved for my house'.
I brought the carvings to wooden boat shows with my and my partner's handmade seagoing kayaks, and people flocked around our table/booth. 'Can I get this on the kayak too?' Not one sale! The only money ever made by it was doing carvings on wooden urns for a local animal or pet cemetery. In similar fashion, I had an offer from a company that did bronze bas relief plaques for tombstones for a one-time purchase of my software! Needless to say, this didn't help with my emotional state, Stephen King references aside.
