I cant speak for the writers on here but I believe the point is that technology starts with the shortfalls before eventually replacing it all.

We are saw this in the States with taxi drivers. There was a shortage, in came Uber, hence no shortage of drivers.

You are right, it will be interesting to see what they pull off and how they can automate. I do believe there are many jobs that are better if people do not do. They are horrible and unsafe.
