Maybe. It depends what you count as part of cooking the steak.

I need to go to the market, find the steak I want, and purchase it, get it home, and put it in the fridge.

Then when I want to cook it I need to find it in the fridge, unwrap it, season it, and let it come up to room temp.

That's all before you get to the actual cooking.

The self driving car already does everything.
