I watched a show over 20 years ago that showed a fully automated robotic kitchen at McDonalds. I can only assumed they have continued to evolved it and perfect it as the technology has improved. I think it’s simply a question of when it hits the tipping point on cost.

There may also be an issue with logistics when it comes to making sure the machines keep running if there is a problem. They can barely keep the ice cream machines running.

True, that’s a good example of the commenter’s “last 5% is the 95%”
