A few formulas I came up with and want to save.
S = 1/I
The measure of entropy is inversely proportional to that of intelligence. So this might be a catchy little way of expressing extropy.
AI > I – AI
The measure of so-called artificial intelligence will exceed the measure of “organic” intelligence before the previous formula will become of any practical consequence.
These would be catchier if there was a neat symbol of intelligence. Oh well.
