Earlier quoted context omitted.
There is one key difference between reality and simulation. In reality you have to spend energy to remove noise. In simulation you have to spend energy to add noise. Or perhaps more accurately, all objects interact in reality and energy needs to be spent to prevent interaction, while simulation requires energy to make objects interact. But it’s even worse than it sounds at first, because you need to spend energy not…
Perhaps a foolish question but does “simulation” necessarily imply calculation or is that just an extension of our current evolution of computing technology as an analogy for what a simulation would be? I’m not convinced the one necessitates the other.
Calculation may be the wrong word for what’s necessary for a simulation, but I don’t think you can have a simulation without something analogous to computing. But the computation may look foreign, think analog vs digital computers. I mean, what would it mean to simulate something if you weren’t interested in finding some measurable thing? How do you seperate the ability to observe the simulation and not be able to measure anything? I may be too steeped in engineering to be able to answer this, since the last thing I simulated was an analog circuit. But I also studied artificial life, and even there the goal was to learn something about life.
