And I am calling Amazon’s “just walk out” service also a con because it was touted as automatic, even if also being mostly human labour.
That’s not what a con is. A con is a deliberate scam. Amazon’s automated checkout simply didn’t function as effectively as intended. They presumably lost money on the venture because the automation was unreliable. Nothing about this situation was a deliberate attempt to pay over 1,000 employees to check an automated system’s work.
The Mechanical Turk is an interesting story and I’m glad you linked it, but it’s not all that similar.
