I don't know how I feel about this. I believe humans may enjoy work - I often say that if I won the lottery I would still sit in front of a computer coding and experimenting, creating software because I enjoy it - but that's not where the value of being human comes from.
I think having to work and enjoying doing a specific job are two different things, and I am just lucky that that diagram is a single circle. Many, if not most, people would not be doing the job they are doing given an alternative.
When the needed work is fully automated and done by machines/AI people will find a better use of their time. I believe our current economy model and social architecture is not equipped for that shift, but that's another long story.
