You'd be surprised. AI is just a catch-all marketing term, see for example IBM's Watson umbrella brand, that's sold like advanced AI but has had tons of fiascos, and is shown to be different sets of often simplistic implementations.

In this case, there's excellent reason to be sceptical about whether the service has a remotely adequate dataset, because even if lie detection were a simple problem, how on earth are you going to get calibration data involving hundreds of data points of real airline passengers lying about having weapons in their luggage or intending to overstay their visa? Never mind calibration data by gender, ethnicity and nationality...
Usually when people say 'AI', IBM included, what they mean is fairly trivial machine learning. Machine learning requires a dataset to learn on.

You could do it by watching film of interactions with border agents when it is still unknown whether or not the person was lying, and then use whether or not they were caught smuggling (or whatever) ex-post as your ground truth.
You're going to need a lot of film. Good luck picking the controls for that that ensure your ML system picks up on subtle differences in humans that are lying and not glaringly obvious differences in appearance, accent and even background noise between the footage of the convicts and the control group...
I assume you would isolate the people in pre-processing, and do feature extraction of things you might think are interested in. Yes, it'd still require a lot of data, but that data may exist somewhere. A lot of these things are filmed.
From CIA, and TSA, to your local police department, everybody would have jumped all over it.
This is some vendor managing to sell some BS to bureaucrats (probably with the required bribes).
If CIA had it, you wouldn't hear about it. I don't see any reason why these countries couldn't pilot it for their border security before TSA, though.
FWIW, polygraphs are still used for security clearance screening. So, they are at least accurate enough for that use. They get a bad rep because they aren't admissible in court, but it's not like they have zero correlation to truth telling. They are still quite accurate.
a) it'll work,
b) it's actually any sort of AI,
and that, for example, even reputable companies like IBM can peddle all kind of shit as AI.
So, IBM was used as an example of a common practice, not as some logical axiom that "because they did it, nothing AI will ever work". Example != logical necessity.
It does, however cast doubt, especially for such a thorny problem as "lie detection", that nobody has, thus far, solved.
Even if all this "AI" does is match the quality of a polygraph, it is probably extremely useful in screening people rapidly at the border.
You obviously don't work for IBM :)
A skilled IBM Watson sales consultant as capable of selling simple linear regressions as Big Data AI!
While I don't disagree that "AI" as a term is being abused, the distinction you're making seems very much a philosophical one.
Where did they get that dataset from? Did they ask a bunch of people a bunch of questions and then hired private investigators to verify the answers (and then hire extra investigators to cross-verify answers given by the previous bunch)? Because beyond something like this, there's no known way to create such a dataset.
I think it's unlikely that they'll be perfect, but they may very well be good enough to filter people for further, more intensive screening.
