That's mostly correct.

Now you're talking.

I personally despise AI, but also don't see the Semantic Web as having
*anything* to do with it.  Perhaps there's some overlap, I don't know or
care.  I just know that the Semantic Web helps me get my job done today,
in a manner consistent with how the rest of the Web works (hypertext).
Web services claim to be able to help me with these problems, but in a
very similar way to other architectures that failed on the Internet
(such as CORBA/OMA).

If there are two ways to solve the same problem on the Internet, where
one reuses Web architecture, and the other uses a failed (on the
Internet) architecture, I know which one I'd choose every time.
