I was sort of thinking the opposite here is more interesting. I just want to text to a blackbox:
"FOOD"
And a short time later food (possibly Soylent to keep the baby food aesthetic right) shows up. If I can do this while wearing a VR mask showing a strange new world with bigger people that talk, even better. I want to be an infant again.
Maybe they can add a feature where it can hear me shriek out and automate this process.
In your scenario the UX may be broken since Seamless can do this much faster I think?
