I think that is a lowball estimation, but whatever. Humans rapidly change the world. That is the one constant of humankind, almost our defining trait. We change things. That’s the way it is. We don’t bemoan the loss of typesetting do we? Or the Cartwright? Or the weaver? Or the flint knapper? Professions die. New ones are born. There will always be work. It’s just the nature of work changes. Learn to adjust. PS Universal basic income is going to be a thing. It’s a near inevitable outcome of automation. Adjust your mind to that idea now.
