Sure, but Watson isn’t really a product and IBM isn’t really a merchant here. There’s never going to be a Watson review anywhere because (AFAICT) Watson is just a marketing name for a wide range of technologies, none of which do any of the stuff shown in the TV commercials. That’s the problem.

I don’t even know who those ads are targeting. Anyone who knows anything at all about this stuff will be dismayed at the sheer BS of it all. Everyone else seeing the ads isn’t in a position to steer customers towards IBM for all their AI needs. They really need to kill the whole ad campaign, surely it’s doing IBM more harm than good.

Remember these ads?

No, it's bad because it drives down the potential market value for good products that could become available in the market because the market expects that all AI is inferior to expectations.

Temporarily. Once past (and possibly during) the "Trough of Disillusionment"[1], products that really do solve problems that people are willing to pay to have solved will do very well.

IBM can bullshit it's way through a coming "AI Winter"; startups might not be able to.

How do you "compare" multimillion dollar custom IT installations, before you buy?

By having people who aren't working for the vendor who know things about such installations assess them before they are bought.
