Self checkout in supermarkets apparently is quite a rocky thing, some chains see profits go down after implementing them. The potential for catastrophic mistakes in LLMs is very high, like ordering 3000 big macs.
Sure in the case of 3000 big macs it would be caught by the buyer or the cooks, but ordering 6 instead of 3 will not. This will cause complaints, complaints need more people to handle, etc.
There was a fun video floating around a few days ago where someone tried ordering 18,000 cups of water... It certainly got them a human being lol
Honestly those problems will get sorted
But I wonder what the effect will be like otherwise, is it gonna be a turnoff knowing you're talking to a robot?
Like what if your cafe barista's were replaced by robots?
Maybe I wouldn't mind so much at first but I'd probably just switch to some place where there were baristas, because why wouldn't I just get a canned coffee from a supermarket if "cheap" was all I cared about
