Whatever happened to the RFID concept where they (not Amazon, but others) previously envisioned attaching small, cheap RFID badges to all items and then you would just do one big, quick scan at the end and it would read all the RFID tags in your cart at once and you could walk out?

I like that idea better, honestly. It's more accurate and doesn't require video monitoring and all sorts of AI/ML/DL algorithms. Though, I don't know the practicality of attaching RFIDs to everything, nor the cost. And I assume some people would try to just rip them off, which I imagine would be the biggest concern, in addition to having the staff attach them to everything.
