Re: [midatlanticretro] Why old tech keeps kicking
- Actually, most "new" technology has been enhancements and not really new
The computer itself whether realized in switches as the English did or
with vacuum tubes as ENIAC in America represented a new technology.
The change from discrete elements to integrated chips represents new
tech as does the conceptual change that permitted both personal computers
and internet communications. All else are merely refinements within
a paradign. Granted that the speeds we take for granted were thought
impossible when we were so proud of our 8086's, but that change is
evolution and not revolution.
bs being a stickler for semantics.
