My group at work consists of six engineers. I'm certain that by 2030 it will be no more than four getting more work done than today. Automation won't replace us all right away, but it will reduce staff. Too much of what we do is repetitive not in specific details but in concepts. After watching two YouTube videos on it I'm half convinced I could replace a whole engineer today after a few days of messing around with TensorFlow (and maybe backend access to our real time grid model (unlikely to be granted)).
