All I have to work on is sensory data also. I can't be certain that there is a 
"real world" out there, and even if there is, all I can possibly do is create a 
virtual reality in my head which correlates with the patterns of sense data I 
receive. Certainly, it is ambiguous, and that is why we have science: we come 
up with a model or hypothesis consistent with the sense data, then we look for 
more sense data to test it. Any machine which looks for regularities in sensory 
feeds does the same thing. Are you saying that such a machine could not find 
the regularities or that if it did find the regularities it would thereby be
