Changing from pegs to machine tuners
Instruments- discuss specific features, luthiers, instrument problems & questions
Point well taken! On the other hand, an oldtimer might easily have also said "Why would i buy or order fancy 'fret wire' when i can just use these perfectly fine and useful fence staples I've already got right here?"
My husband is very practical and handy, and i can envision him saying something just like that. 
More rambles- oldtime builders probably didn't think they were doing anything 'out of necessity', they were just clever in using (or making) what worked well and produced the desired result... something people did plenty of in daily life without thinking about it much.
These days, we are drowning in specialized tools and gizmos for doing literally everything... frothing milk for our coffee, car seats that warm our butts, weird red light masks to improve our complexion, and yeah clipping on electronic tuners instead of simply going "bim bim BOM".
I like to think about these funny things.
