Is some places (maybe mostly in the US) it's bad. But the idea of fast food -- to have ready-cooked, mass-produced food that you can get quickly -- isn't all that bad.

Is Ekiben (https://en.wikipedia.org/wiki/Ekiben) is fast food? It's ready-cooked, it's mass-produced, and you can get one very quickly. Is sushi take-out fast food?

They are still not as good as a meal that is carefully prepared by a housewife/househusband. But I do think the mass-produced substitution can be good enough, and that's why I don't think we should make the conclusion that AI therapists/companions must be so bad too early.
