I clicked the link imaging a moving robot that chopped/prepped food. It was the sous-chef part that made me think that. I don't think I would have interpreted robotic sous-vide cooker the same way. That being said, I definitely think 'smart sous-vide cooker' is a better description and more useful tag-line.
I understand that, and I'll admit I didn't mind the ambiguity when I was choosing headlines.
Ultimately,what made me choose the "robotic" one was that we're not trying to build a smart sous-vide device, sous-vide is just technology. We're trying to build a quiet servant. And that won out.
