I honestly don’t understand why they didn’t just use RFID for the grocery stores. Or maybe they are, idk, but it’s cheap and doesn’t require much training to apply. That way you can verify the AI without needing much labor at all.
Then again, I suppose that point wasn’t to make a grocery service, but an optical AI service to sell to others.
That said, a lot of people don’t seem to understand how AI works, and the natural response to not understanding something is FUD.
