How bad is that artificial intelligence?

In the comments at last night's café post, Freeman Hunt wrote:

Another exhibit in the case that artificial intelligence is not so great:

Drinking in America: Our Secret History
$20.52

NEOPlex 3' x 5' Flag - "A Spliff A Day"
$6.95

Amazon is offering these as things it thinks I might want to buy.

I responded:

Freeman, "Drinking in America: Our Secret History" is a book I blogged about here very recently. "A Spliff A Day" isn't something that ever appeared in the text of this blog but it is in a photograph from Saturday, on a flag. That means that Amazon widget sees what's in writing in a photograph. Pretty impressive.

You may not want to fly a "Spliff A Day" flag. But you were reading a blog with a picture of one. Frankly, I'm amazed that the Amazon widget knows what's in the photographs.
