The way he clung to „what do I do first” makes me think that the whole conversation was scripted in the prompt and AI was asked to reply in specific way to specific sentences. Possibility not even actually connected to the camera?

Yeah as a fully integrated system and the selling point I'd expect you'd say something like "Look again I think you're getting ahead of yourself".

Maybe the tech wasn't quite fool proof and they tried to fake it and then the fake version messed up.

I distrust meta (and hate these voice assistants) as much as the next guy but to me it’s obvious that you would prepare the prompt and use pretty much the exact phrasing. Also, repeating yourself is normal if there’s no response at all. If it was truly all fake why not just cheat outright and just prerecord all of it?
