On the supply side, the best FUE doctors are specializing and doing only it. And I get the impression that there is a tendency for the new doctor to choose do be FUE only too.
I think except for Dr. Konior, the most demanded docs are FUE only too. So if the current trend continues, we will see more FUE and less FUT in the future.
Regarding hair cloning, after Organ Tech (Tsuji) went bust, there is really only company working on it:https://stemsontx.com. There is a lot of info about them on the net and I think they have a real chance of delivering the first version of their treatment within the next 5 years. Their version of hair cloning will be like a traditional HT but with unlimited donor supply. HT doctors will be needed to implant the cloned hairs - only instead of implanting a graft, it will be a scaffold with cloned cells inside it, a "hair germ", that will result in a hair. So hair cloning will be like the next version of HTs and the current docs will be able do adopt it.
This is a 2019 video explaining how it will work. I believe they are more advanced now.
If it works on humans it will be the holy grail.
