Have you noticed that despite the supposed information overload problem the incidence rate of your “how did I not know this!” flow of input-Aha moments has been slowly increasing over the last few years. Not signal-to-noise ratio, actual absolute signal levels? Mine has.

Signal to noise (SNR) is actually a bad measure for intelligent systems. You’re not a simple amplifier or something. Noise should be weighted by how costly it is to tune out, and signal by how costly it is to tune in. Most noise is very cheap to cut out.

No it’s not. It’s a sort of naive physics measure of relative spectral power. The cost I’m referring to is conscious info processing cost. If you cut out 90% of noise wattage with say a single bandpass filter it’s cheap noise.
