Work is any activity involving mental or physical effort done in order to achieve a purpose or result. Not too long ago I was watching a documentary on YouTube about the future of work. The documentary had the guests presenting two diverging views.
One view was that robots will replace humans at a scale that will disrupt our current societal construct as it is. The other view was that robots will always be complementary to humans, just as they have been since the mass manufacturing started in the sixties and seventies.
From my perspective, there will always be work for anyone who has a valuable skill or experience to offer the marketplace. No matter what influences the marketplace faces from technology or administrative policies, there will always be work for you.
