I have no problem with that; but your phrasing is too fuzzy for me to
follow the reason why you reject both Schmidhuber and the "personal-comp".
Do you really mean that your "theory" would made you say no to a doctor
presenting you an artificial brain (even with a very low substitution level
description of yourself) ?
Remember that my point is just that is we are machine then physics is 100%
derivable from computer science. (But even if we succeed to derive 100% of
physics from comp this would not be a proof that comp is true).
