Hmm..took my brain several orders of magnitude longer to warm up than a 6L6 power tube.

AI suggested that I was being generous with my 0 dB S/N for social media, it should be -∞ dB. Good catch.

It also didn't like my unit compatibility (reminding me of the utility of unit analysis), but remember that my '+' is overloaded--most programmers would probably write:

    int plus_ungood(int bytes, double SNR);

dropping the units. Of course we programmers also add geometric points together without dividing, which is mathematical no-no too.

I guess I'll put this on my TODO list for a fun project--"Relativistic Shannon: A Critique of Pure Reason on Social Media":

    Einstein wasn't afraid of arguing across time with Newton, nor should we be afraid of arguing with Shannon.  Arguing on social media, well that's a different thing altogether....[continues for 7000 pages]

I did learn what semantic density was without AI's help, postulating that it would be involved (viz Graham above) using my alarmingly down-trending cognitive abilities.
