NOISE-SIGNAL

NOISE-SIGNAL We have had a tradeoff in filtering (noise) based on costs production-transmission: letters are semi-filtered but slow; telegrams are v. filtered and fast (v. high-signal); phone calls less filtered and fast;email is unfiltered & fast (consider emails/day saying NOTHING). 1) The combination letter + telegraph +phone seems vastly superior to email. 2) The telegraph might be the most significant invention.
