Not only that, I think Joel is placing far to much emphasis on
computational theory. People draw pictures and imagine images which
are continuous in 2D. I know that these can always be digitized and if
done on a sufficiently fine level the result is indistinguisable from
continuous - but this doesn't prove that there is no continuum. Even
quantum mechanics still relies on a continuous psi functions defined
over continuous space-time. It may be possible to *represent* this
discretely, but even if that is possible it doesn't mean it is
impossible to represent it using a continuum or that there is no
underlying continuum. The argument that our understanding or our
descriptions must be discrete is not convincing because it is equal
true (or false) that our descriptions must be finite and even *small*.
