I'm glad to hear you aren't grumpy in person... but you do come off
that way online.. :-)

I understood this to be your position.

Google runs on a supercomputer too. The same basic kind of
supercomputer. Also, an iPhone has the computational power of NORAD
circa 1965... so lots of extra computation can buy you a lot, even if
not AGI all by itself.

I think answering questions is a generally useful task.

Of course you can. Put it online, time share it, put it in the cloud.
All this works fine. Most doctors wouldn't use such a system for more
than a few minutes a week since most of their work is pretty routine.

As for IBM making money from Deep Blue, I would ask did Americans
benefit from the space program? Research isn't made to directly make
money, but to lead the company in directions that will make money.
Last time I checked, IBM was still profitable. Without research, they
soon would not be profitable.
What Watson tells the world is that IBM is still relevant. If that
supports their stock price, then the Watson team has earned their
money. There are now world class chess programs that run on cell
phones. In ten years, there will be Watson like programs running on
cell phone sized devices, but working better.
I'm not impressed by Watson mistakes. We KNOW it isn't intelligent, it
just does what it does better than most humans. Over the next three
days, we'll see if it does what it does better than the very best
humans. Ken Jennings lives around here somewhere. I am kind of
surprised I've never run into him.
