The universe doesn't have to be kind and make all problems amenable to insight....

There are only a certain number of short programs, and once a program gets above a certain length it is hard to compress (I can't remember the reference for this, so it may be wrong, can anyone help?). We can of course reorder things, but then we have to make things currently simple complex.

That said I do think insight will play some small part in the development of AI, but that there may well be a hell a lot of parameter tweaking that we don't understand or know why they are so.
