In fact, there already are jobs where human being is not need anymore or is less needed. For example cashiers in shops. Stores service is being replaced by self services. And this system works very well for me as customer. Queues are smaller and service is faster.. 10 years ago I couldn't even imagine that it is possible.. Nowadays I use it every day.

I didn't belive in self-driving taxis last year.. today it is on testing already..

World is changing very fast..
