The doomsday called automation?

From the introduction of turnstiles to the increasing mechanization of assembly lines, automation and introduction of robotics have become synonymous with doomsday for millions of workers across the globe. A lot of it is hyperbole. Let me give some reasoning.

1. The global community has come to face with such a possibility, in which millions of jobs are destroyed permanently by automation and human labour is replaced by robots, on multiple occasions before this. On every such occasion, such fears have found to be unfounded.
2. Automation displaces, more than it destroys. With reskilling, most such displaced labour becomes able for employment again by the newer industries which are constantly emerging. But there comes a difference. Historically, every such cycle has been accompanied by large doses of increase in productivity, which is always beneficial.
3. With the increase in productivity come numerous other benefits, same or more work is done in the same or even lesser amounts of time, increased earnings/spending and so on all of which leads to the emergence of increased production which employs more labour or emergence of newer industries itself, which again generates more employment avenues. All of this is commonly referred to as 'offsetting effects'.
4. Interestingly, what we overlook is that all these offsetting effects are invariably accompanied by an increase in productivity of the existing labour forces and higher standards of living for the society overall.

All of this is evident from how over decades and phases of automation, the rates of unemployment have more or less been in manageable ranges, except for economic recessions of course. The ever-increasing pool of labour has managed to keep itself employed and working, all the while as we witness increasing standards of living cutting across societies.
