PN writes: In our natural world (you know, reality and the like), everything has feedback. It’s a fundamental contract we have with everything else in existence that if I do something, one or more of you things out there will do something in return. It could be a simple and singular cause and effect or it could be an endless string of reaction after reaction. For example, if I poke a bear, feedback would be the bear waking up. If the bear notices me, I will run. Both can be viewed as isolated scenarios of “if this, then that” but as a whole, it can also be viewed as a chain of if I poke a bear, I should run.
