I work in an automated factory. We will not get to zero humans in the loop anytime soon. However we have drastically eliminated the number of unskilled humans required. I've not understood why fast food doesn't use more of the sort of automation we use. I'm guessing it's still cheaper to get more flexible humans to do most of the work. But at the scale they operate I think they might be able to spread the R&D cost and purchase at a massive scale. So I'm surprised automation has not taken over yet. At least to the point that there are very few required to run the machines.
