i think the point is that when designing clocks we didn't just attach some gears and a timing mechanism and some hands to a sundial, we threw the sundial out. computers are complex because we hardly ever remove anything, and we still bare their cost aeons after they're relevant.

Yeah but clocks generally don't interface with other technology. Trailer hitches and screw drivers do. There is a whole slew of different hitch adapters. And, most of us have or at least have seen screw drivers with a set of attachable bits.
