Are We Living inside Massive a Computer Program?

EXCERPT: Are we living in a video game? If so, the joke is on us, says cognitive scientist Joscha Bach. When people debate the possibility of human existence as a simulation, it's predominantly assumed that we are the players. Our overlord simulators are watching us, right? Well, that doesn't seem to gel with the amount of detail present in our world and the observable universe beyond. Why did our cosmic creators bother to code trillions of galaxies into the viewfinders of our telescopes? The Higgs boson, for example, is not necessary for our existence, so who would have the time to add such irrelevant frills just for our amusement (maybe the simulators had a really great intern that summer)?
The answer? It's not made for us. According to Bach, if this is a simulation it's unlikely that we are the main attraction and much more realistic that the simulators wanted to make a model of a universe to explore hypothetical physics. That tiny blue dot with primates mixing concrete all over the surface? "We are just a random side effect or an artifact of the fact that evolution is possible in this universe," says Bach. But, that explanation is purely hypothetical because Bach is confident that we are living in base reality. However it's not bubble bursting from Bach: while we are not living in a simulation, we are living in a computer program. How can that be? Above, he explains why, and also gives his response to the 'game console probability' hypothesis popularized by Elon Musk....

Consciousness is not a thing, but a process of inference

EXCERPT: [...] What’s remarkable about this sort of repetitive, self-organising behaviour is that it’s contrary to how the Universe usually behaves. Everything should actually get more random, dispersed and chaotic as time marches on. That’s the second law of thermodynamics – everything tends towards chaos, and entropy generally increases. So what’s going on?
Complex systems are self-organising because they possess attractors. These are cycles of mutually reinforcing states that allow processes to achieve a point of stability, not by losing energy until they stop, but through what’s known as dynamic equilibrium. An intuitive example is homeostasis. If you’re startled by a predator, your heartbeat and breathing will speed up, but you’ll automatically do something to restore your cardiovascular system to a calmer state (following the so-called ‘fight or flight’ response). Any time there’s a deviation from the attractor, this triggers flows of thoughts, feelings and movements that eventually take you back to your cycle of attracting, familiar states. In humans, all the excitations of our body and brain can be described as moving towards our attractors, that is, towards our most probable states.
On this view, humans are little more than ‘strange loops’, as the philosopher Douglas Hofstadter puts it. We all flow through an enormous, high-dimensional state-space of manifold possibilities, but are forced by our attractors to move around in confined circles. We are like an autumn leaf; tracing out a never-ending trajectory in the turbulent eddies of a stream, thinking our little track is the whole world. This description of ourselves as playful loops might sound teleologically barren – but it has profound implications for the nature of any complex system with a set of attracting states, such as you or me....
