Automating servers has been tried since the early years of this decade, by McDonalds in particular, and that same company is now hiring again paying $15 per hour for those same very simple positions.

Automation isn’t going to happen like that, although I am unsure what the obstacle is for something as basic as fast food.

All the tech is there. Automatic burger machines have been here since the 70s. Ordering can be done through a phone app. Where is the bottleneck?

Now if selling hamburgers can not be automated I would like to know how something more complex like political strategism or software engineering or market analysis is supposed to be automated.

Higher paying jobs take more skills, experience and judgement so are harder to automate. The first jobs to be automated were repetitive labour.

Yes but they were still higher paying jobs than the server at your local eateries.
