Alan Kay: Shannon Gave Us a Way of Dealing with Noisy Channels

Alan Kay performs an improvisational avant garde layered audio feedback loop about Claude Shannon, live online during Kristen Nygaard's 100-year birthday celebration.

Alan was scheduled to talk about how encountering Simula sparked his early thoughts about objects. During setup, somebody had the live stream playing out loud near an open Zoom mic, so his own voice kept arriving back in his ears about 21 seconds late, over and over.

What he said was not random: "Shannon gave us a way of dealing with noisy channels." And: "I think about that almost every day. I realize what the fuck is going on and it's just so amazing." Shannon's noisy channel coding theorem is the math for exactly the kind of channel that was garbling him as he praised it.

Like a time-out timer (TOT) on radios?

When activated, the Time-out Timer starts counting the moment a user begins transmitting. If the transmission continues beyond a pre-set duration, the timer automatically cuts off the transmission. This mechanism compels users to be concise in their communication and relinquish the channel, allowing others the opportunity to transmit.

Edit: No, it's more like a scheduled lockout. You can only talk when it's your turn. And the assumption is that the clocks on each node are synced:

Every node has a notion of the global time and uses this notion along with the static schedule to establish when it should send messages.
