These models are nowhere near that for now, but I'll be watching to see if the big investments into synthetic data generation over the next few years get them closer.
They can be competent enough to cook meals in a controlled environment: (environment built for machines and specific dishes), without ever being able to replicate the same in a human restaurant.
There are a few companies that do robotic cooking, and it has its challenges due to the above reason. I am not aware of the cost problem though.
How cool would it be if this replaced someone at Subway though
