You probably realize this, but here's chapter and verse on why analog was superseded...
The thing that makes digital attractive was actually pointed out in the 50s by John von Neumann: every digit you add to the representation buys you another factor of 10 (or 2, in the case of binary) of precision. I can't find a reference but it's in a famous von Neumann paper, and is celebrated these days by Neal Gershenfeld as one of the major things that makes digital tech work.
