Hi Bruno, I don't understand what you mean by computations being infinitely far away. In the UD deployment, which I will wrote UD*, all computations begins soon or later (like all dominoes falls soon or later in the infinite discrete dominoe-sequences). All computations reach any of

Hal, I have entertained quite similar musings some time ago, and this led me to a position I called naive materialism NMAT some time ago on this list - that causality does not matter, and consciousness would supervene on the material states directly - and both backward and forward versions
