The expectation that recruiters will still have a right to exist in their field in 50 years is based on hope. Hope is postponed disappointment, and those 50 years could quickly become 25 or even less. It is not technology determining whether robots will take over many human tasks; it is humans themselves. The biggest problem is acceptance.
Once people accept that they are not the only ones who have the privilege of making mistakes, technology reduces humanity to the remaining 5%.
The future will show when exactly this happens. You cannot write history in the present. Hundreds of years from now, people will surely seize a moment as the tipping point. We are in a transition phase where things happen step by step without you being aware that the tipping point has been reached.
We will not be able to stop this anymore. All you can do is hope that you last until retirement. Perhaps you can benefit from it. People do 80% of their work in 20% of their time. Just ask that pilot.
My question to you is:
What will ensure that recruitment can run on autopilot for at least 80%?
