Why do we think most AIs unintentionally created by humans would create a worse world, when the human mind was designed by random mutations and natural selection, and created a better world?
As far as AI designers go, evolution has to be one of the worst. It randomly changes the genetic code, and then selects on the criterion of ingroup reproductive fitness - in other words, how well a being can reproduce and stay alive - it says nothing about the goals...
What are you implying here? It's clear that *we*, or at least *you* exist, in the sense that the computation of our minds is being performed and inputs are being given to it. We can also say, (with slightly less certainty) that observable external physical objects such as atoms exist because the evolution of their states from one Planck instant to the next is being performed (even when we're not observing it - if the easiest way to get from observation t1 to observation t2 is by computing all the intermediate states between t1 and t2, it's likely that the external object exists on the entire interval [t1..t2]). This is my conception of an object's existence, that the computation of an object's state is being done. What is yours?
