During my studies I did some exciting simulations of a fuzzy logic control 
systems (simulated a control of a gasturbine and a control of a ABS for an 
About half a year ago I did some small tests to see if it was possible to get 
some AI using fuzzy logic in Drupal. After investigating this for a short 
time, I concluded that PHP is not suited for this, and that Drupal is too 
HTML/content oriented (as opossed to data-oriented) to handle this.

In order to get any sort of AI and / or learning system in, we need:
 * external libraries, PHP is Just Not Ready for this. (performance, memory, 
and library wise)
 * approach Drupal pages more as objects and as datamodels, rather then the 
current way of passing around glued together strings. 
(theme/module/nodeapi/database all have private glueing systems, there is not 
a central place where one can access *all* data, including blocks etc, on a 
data level, where you can poke around in metadata or objects.)
  things that are interesting are:
   * theme_list lists, they tell us that any item in any such list has a 
certain relation to the other one.
   * node teaser lists: Same as above. 
   * user lists: any user in any list has a certain relation to the other 
users in these lists. We use several such lists. We must fins a way to filter 
out tabbed browsing, then we have very valuable data on the behaviour of 
users on a site. 
   * comment - node relations. The content of a comment tells a lot about a 

This is very interesting. :)
