To be honest, tech has been applied to those markets largely in making patronising the craftsperson largely unnecessary for those that don't want to go and visit a kindly old man to have their old-fashioned and sometimes entirely unique mechanical device attended to to preserve its sentimental or status-boosting value. One source of inefficiency is a target market that often doesn't want inauthentic parts, never mind the perfectly adequate mass-produced disposable replacement. I suspect hundreds of years of innovation when clockmaking was important has done a good job of ensuring the devices and processes they use are ideally suited for purpose and they've got access to ongoing innovation in precision engineering techniques from other fields if and when they need them.

I'm not surprised young people aren't entering the business if their status hasn't progressed beyond "apprentice" in 20 years!
