“The tyranny of live” is a phrase we use around here to explain some of the archaic constraints surrounding the behaviors of phone calls and tactical radio communications. In the “olden” days, communications were carried by a wire and the wire had to be in place between the communicators. Then things evolved so that the communications traveled over the airwaves, but the devices created the waveforms directly from live sound and converted the captured waveforms directly into sound. These physical behaviors created the sense, which some still accept, that voice conversations are a live media. Well, we don’t actually believe that, but we accept systems that still enforce this tyranny.
We all know that if you want to actually speak to someone now that the phone system has to find them, alert them, and capture their attention—that is, subject them to the tyranny of live, because that’s what you want to do. But did you realize that when you are leaving them a voice message that the system has the same behavior? It requires a “live” connection between you and the callee’s voice mail system (which doesn’t actually care that you are there at that moment)–with all the overhead that implies.
Of course, with today’s technology we don’t have to go straight from waveforms to sound or vice versa; we can digitize the data and do whatever we can imagine with it. We can save it; we can send it later; we can broadcast it, email it, transcribe it. (Most of us don’t do all these things with voice because it’s too much hassle to have 5 applications to replace our phones—even with all its limitations.)
The worse effect of accepting the tyranny of live is the fact that in tactical communications, the only messages you get are those that you can receive live, as in, real time now. Most of the radios send messages as they are spoken and transform the incoming messages directly into sound as they arrive. If there is any glitch in your real time network, a little bandwidth shortage, a piece of waveform disrupting hardware (an air conditioner, say), a bit of a hill, you never, ever receive that message. It is lost to you. And if no one repeats it at the right moment (how efficient is that?) you will not hear that message to get out of the building.
Things have to change for us to succeed in revolting against the tyranny of live, but it turns out that the technology is at hand in these days of IP networks and capable devices. And in the future your communications can happen when you want, and how you want, and you will spend as little “time” as possible making them effective.
Having it always work just the way you want is living with no tyranny at all.
