On my workbench are the pieces of a thoroughly analog electronic musical
instrument whose most advanced components date back to the early 1970s.
One of the more interesting components in there is a rotary encoder
constructed out of a large-diameter wooden dowel that's half-covered in
metallic flashing cut at a diagonal (with respect to the long axis of the
Riding atop this cylinder are thirty some-odd brush-leads such that
rotating the dowel causes some number of them to contact the flashing
(and, thus, complete a circuit with the common wire at the lowest
position). Each of these leads has a separate line back to a complex
These days, an identical device could be made from far less hardware and
at a far lower cost, while having additional resilience against humidity,
corrosion, and physical shock. Due to the nature of solid-state
components, the inattention to quality control may, indeed, justify it
being called "cheaper" even while being vastly better in every
specification that matters.
I appreciate that my 21st century Bimmers do not require double-clutching,
do not burn oil with alacrity, do not require choking when cold, and get
25+ miles to the gallon even when I drive like my hair's on fire. The
2000-mile service intervals that accompanied the same time period in which
that instrument was built aren't any sort of luxury I desire.
Sometimes time just marches on and there isn't any conspiracy to it.
