- Open Loop
- The temperature of the surface of the moon is a good example. It slams from one extreme to another when it's in the light or dark.
- Controlled by a Plan
- The thermostat controlled temperature of a house is a good example of this. A computer or some electro-mechanical device turns a furnace or air conditioner on and off based on a measurement. There are countless examples of a computer, or a simple human-controlled "algorithm" controls something like the level of water in a dog bowl, or the amount of nitrogen in a farm's soil, or the interest rates of an economy, etc...
- Self Regulating
- Almost every living thing, and even ecosystems is self regulating. Blood pH, O2 saturation in the blood, and body temperature are examples from the human body. The temperature of the Earth is "self-regulating" compared to the surface of the moon. There's no obvious "plan" or algorithm at work coordinating the opposing mechanisms, but they operate to produce a stable equilibrium that can drift around over time.
How often and how much to eat is currently a problem for many people in developed countries--all kinds of food is available in abundance. People generally adopt an abstract "plan" to control their diet, that is they eat on a regular schedule, and eat an arbitrary amount even though their activity level might vary quite a bit day to day. Most people get overweight as a result (including me). Some might adopt "algorithmic" control of their weight and actually count calories and weigh themselves every day.
The propensity to adopt algorithmic control versus learning to "listen" to body cues is pretty telling. It's a pretty good example of how we generally tend to live in "the matrix", that is our internal Thomas Anderson experiences reality via a model, essentially.
The internal strawman is really an alien on Earth, even in the body. He speaks a different language. This simple example of "diet" is a good one to understand what I've been writing about for years. That strawman could, instead of developing an algorithm and model to control "weight", meld his consciousness with the ancient signals and language of his body.
In theory, that "language" of nature that's speaking to us about hunger is "out there" in nature too.
