Yep.
In the past a person could have one skill or job for an entire career.
In the near future, we will have to continually retrain for existing jobs (changing) and new positions.
I know the sentiment, but I don't believe that is true. I think we have always had to face change throughout our lives. My father-in-law was planning on being a musician, then WWII came around and made him a sailor, then through his post-war education he became an accountant, and now he's back to being a musician.
My grandfather was raised to be a farmer. The depression forced him into a position to abandon farming for a job with the Rail Road. When he went back to farming, in the few years he was gone, most folks had mechanized and he had to hop on that bandwagon to produce enough to feed the family.
Everyone I know had to make adjustments to keep their careers going. I don't see why this should be any different.
