I just read the Spacetime article on wikipedia which argues that the spatial and temporal dimensions (N=3, T=1) are special, since without them no life as we know it could ever exist. It is not clear to me however if a computer (or better an (in)finite Universal Turing Machine) could ever exist at dimension different than (3, 1). Is it the case? Also, I prefer to use a Computeric Principle rather than an anthropic one, given that defining "life" is rather difficult, and yet more defining "intelligent life". Will using a Computeric Principle present problems or would it be just better? I am looking forward to read your thoughts. Andrea.
