But, the refutation: A sufficiently intelligent, self-aware system is
quite capable of modifying itself to make itself MORE ERROR-PRONE if it
finds through experimentation that this makes it more intelligent ;>
In practice, Webmind is plenty error-prone, using lots of approximate
and uncertain generalization. So the problem you describe seems to apply to
situation of hardware plenty...

What I mean is that even if there is a LOT of data, and it's highly varied,
there is still
a certain amount of overfitting that is inevitable.
On the other hand, the more memory you have, the more of this data you can
keep in mind for use
for new model-building rounds based on new data combined with the old. So
the maximum-memory system
will achieve the minimum amount of possible overfitting given the data.
