To me these all sound pretty plausible?

You have browser extensions that allow AI to control it. There are apps that create a virtual microphone for text to speech. All pretty easy to get going if you allow an AI to control a computer.

Generating designs is also easy. Just use nano banana or something similar.

I'm more curious about the quality of the output. I've seen some ugly stuff. The article also includes one example (the outdoor seating design).

I'm also curious about the reaction of people to AI running the shop. Do some people decide not to deal with it? Do some people abuse it? In the article there seem to be only positive examples of human-AI interactions.
