That's interesting since my impression if anything is the exact opposite. There seem to be a lot of people trying to apply Bayesian learning systems and expert learning systems to all sorts of different practical problems. I wonder if this is a new thing or whether I simply don't have a good view of the field.

For what it's worth, I consider Bayesian learning systems and expert learning systems to be "narrow" AI -- hence the example I gave of Watson.

I think Ben Goertzel's Novamente project is the closest extant project to a 'general' AI of any form that I've heard of.

I can see that for expert systems, but Bayesian learning systems seem to be a distinct category. The primary limits seem to be scalibility not architecture.

Bayesian learning systems are essentially another form of trainable neural network. That makes them very good in a narrow range of categories but also makes them insufficient to the cause of achieving general intelligence.

I do not see that scaling Bayesian learning networks would ever achieve general intelligence. No matter how big the hammer, it'll never be a wrench. That being said, I do believe that some form of pattern recognition and 'selective forgetting' is important to cognition and as such Bayesian learning architecture is a good tool towards that end.
