Robots are going to take many jobs from humans in the future. That applies to flipping burgers too. Take Flippy for instance: it is a robot that will be cooking up hamburgers at Caliburger. Flippy is equipped with thermal imaging and cameras to detect when to flip the meat based on the temperature and size of the patty.
The robot has machine learning, so the more it flips, the better it gets at its job. More information is available here.
