The statement “My father had one job in his lifetime, I will have six jobs in my lifetime, and my children will have six jobs at the same time.” makes a pithy statement but is generally not true.<p>My father had about 6 jobs in his working life. Looking at my uncles they varied in the number of jobs but none of them had just one, over a working life of more than 40 years each. Thinking wider still, I cannot think of a single person in my parents generation that had just one job.<p>It might be that people average more jobs today than they did in the past. Maybe you can project that forward and guess that a future generation will average more. But to say 6 concurrently is wild speculation and hard for me to take seriously.<p>There is no reason to think our children will have many concurrent jobs. Certainly no more than people do today.
