Nice to know we can beat the machines at something, however other things appear to be a draw.
What’s so cognitively demanding about supermarket checkout? I spoke to several former checkout people, and they all pointed to the same skill: Identifying fruits and vegetables. Some supermarket produce is tagged with small stickers carrying product-lookup codes, but a lot of stuff isn’t. It’s the human checker’s job to tell the difference between green leaf lettuce and green bell peppers, and then to remember the proper code.
There’s something sobering about telling somebody “that’s romaine lettuce.”
