ELI5: How do we have automated robots that do extreme precision engineering, but there are still no cooking robots in restaurants?

Robots are expensive, so unless they are going to save a significant amount of money for the restaurant, it doesn't offer any advantage over just hiring a chef.

Also, some restaurants do use robots - there's a noodle cutting robot that some Chinese restaurants use. 

Also if you have a flexible definition of "Robot," things like sous vide circulators are technically robots, and restaurants definitely use those.
