I have nothing to say about the actual model, but unrelated--why do so many of these demos include people buying things autonomously? Even if I did trust an AI to get everything right, it's not like the AI can read my mind. If I was ordering food normally and without AI, I would want more control over the process--looking over the options, prices, thinking about what I really want. People don't know what they really…
"Oh hey! Here's a demo of an AI planning out a 1-week trip to Paris!" No one in Middle America would just hand their credit card to an AI and let it come up with such a trip!
I wish SV companies took more of the middle-class (and lower-middle-class) into consideration when coming up with such demos.
