That is today...down the road there will not be the shortage of people but, rather, jobs.
When tens of millions of people are being automated out, in a short period of time (10 years or less), this will create an abundance of workers. Of course, many of the jobs that are presently seeking people most likely will be filled by automation.
That is where corporations are focusing their attention....make up for the shortfall in workers, then automate the ones they have out of jobs.
