A sketch I did once during a boring meeting.
Description:
Information content conveyed in any given meeting is a nonlinear function of time, increasing gradually to some asymptotic limit.
Similarly, information value also increases with time but at a much higher rate, reaching a peak at a time that is much, much sooner than the time where the asymptotic limit of information content is reached.
When normalized information value equals normalized information content, the horse is dead.
