Agreed. On a related note, I wonder with the extra efficiency gained from no checkout lines, how much it would offset lost revenue. In other words, if, say, you are able to serve 20% more customers, even if there's 4% more loss from tech bugs (not considering shoplifting), the fact that you're moving more people through the store might make up for it.
If someone buys 45 items, but 3 dont ring up, as long as the 3 were relatively cheap items like a can of beans, as opposed to a $15 jar of spices, does it really matter ? Over time, the system will learn which items "go missing" most often and focus on them specifically for better inventory mgmt.
Maybe this is different, but my experience with recent tech innovations in brick-and-mortar payment systems haven't been positive overall. More trouble than they're worth.
This could very well be different, but the minute the store starts valuing the AI over the customer, I think the store is in for some trouble public relations-wise.
