This is good. I look forward to seeing what happens.

Here is my prediction for how things will evolve in the future, though.
  The first set of learning mechanisms may work to the extent that their
scope is limited, but if they aim for very general (cross-domain)
learning, or if they are used for a developmentally extended period
(i.e. if the system is supposed to learn some basic concepts, then use
these to learn more advanced ones, and so on for a long period of time)
it will start to bog down. The more ambitious the learning mechanism
and the longer it is expected to survive without handholding, the more
the result will deviate from what is expected. And it will "deviate" in
the sense that the quality of what is learned will just not be adequate
to make it function well.

Of course, this is *in no way* meant to be a comment on the quality of
Novamente, I am just trying to anticipate the way things would go if the
complex systems problem turned out to be exactly as I have suggested.

I'd be the happiest person around if it did not.
