Depends, php is perfectly feasible for a lot of AI tasks - look at the spam.module.
It is a classifier. It performs reasonably well.

It is a challenge as well. Depends. From some of the evaluations I've
done some time ago, it is perfectly reasonable to expect a php system
to be used for user profiling and generating adaptive websites. Learning
algorithms are not nessesarily heavy.

Have a look at triana http://www.trianacode.org , you can get a web
services environment wrapping the weka classes with that. And the guys
are experimenting a lot with it. But it is heavy. It is not for Joe X.

There is orange as well:

And I agree with your logic. There is place for such things in a system
like Drupal. That is power on your fingertips.
