Update, I thought of a way to express the parent comment here:
0 + 0 = 0, substituting literal values, dropping the units, for some convoluted overloading of the operator '+'. My TSH (thyroid test) came back from the lab without units this, I guess I'm modernizing.
0 dB S/N + 0 bytes originating information = 0 bytes transmitted (arguably error free to be fair).
Contrast this with P. Graham's comment last year "Why would I want anyone to fail?" on Twitter, which (I'm not a fanboi of Graham or Shannon or Turing, just an admirer of their work), was the most information transmitted to me over any medium, with any S/N that year. Perhaps we should revisit the basis of Shannon's work, in light of what we have learned from the Internet--Einstein wasn't afraid of arguing with Newton. :)
Bye.
