I have a conspiracy theory: I wonder if this is the sort of thing the ultra wealthy want the rest of us to believe. That way we are more easily commodified as labor. We can be put into a spreadsheet or Big Data app to make the 99.9% of us more manageable. We are more manageable if we are more predictable.

It's the flip side to "you are not your job" from Fight Club which ultimately must have got it from the general idea of identification, in a spiritual sense.
