It very much does apply to manufacturing though, and all modern lenses use transistors, are designed with CAD programs, and assembly lines are computerized. The glass itself may be somewhat free of Moore's Law, but the remainder of the R&D, prototypes, and much of the manufacture isn't.
Lenses benefited hugely with the first introduction of computer design in the 70s. Since then, computer design is computer design. More powerful computers provide better products (today's lenses are marvels compared to those from the late 70s), but it's not particularly cheaper because programmers don't get cheaper. Especially not well-paid Japanese programmers.
The transistorized components of lenses are a very minor portion of their construction.
No, to a great degree, the assembly lines for lenses are not computerized (do you have in mind some process out of "Futurama?")--you got rows of women with bins of parts, yes, even today. Well-paid Japanese women.





. Expect zooms to be dominating the dSLR world in the near and medium future until we'll be able to record gigapixel 3D images on our retinas!
