Nope. They're just not used to reading physical 2-D blueprints or to working with small, complex mechanical devices. I fully believe that in making the first 3D computer models, they left out a vital component because they misread the old blueprint and thought it was redundant....and that it took the oldtimers to explain why it was needed.
Same reason Sankyo decided against making a super 8 camera in the early 2000s when they still had their blueprints and even a stash of spare parts. same reason none of the former cassette deck manufacturers can currently make a cassette deck despite that knowledge being only 20 or so years ago.....same reason none of the other former film camera manufacturers has suddenly resurrected an old model. Same reason Technics had to completely reverse engineer and redesign the SL1200 turntable to resume production just a few years after stopping. And the entire SL1200 is probably a lot simpler than a ratchet wind for a film camera. Ever taken one apart?
The skills of an engineer in 2024 are vastly different to the skills of an engineer in 1974. And it will also be true that their engineering staff is much smaller than in 1974.
I think it is very easy to fall into the trap of assuming that making a new, intricate mechanism is quite easy because it's all been done before.....if it were so easy, others would have stepped in years ago.
