Hey, David! Thanks a lot for taking the time to write this up!
You’re point about personal data being a kind of default personal credit is intriguing. However, I’d argue that the value of a single person’s personal data is actually dependent on the person’s “real world” wealth and influence after a fashion. For instance, would the value of the personal data of a lazy deadbeat who lives in his mom’s basement be comparable to the same amount of personal data on, say, a Nobel-winning scientist? I don’t think so.
Overall, I’d hold that it’s the amount of data one person can generate that creates the value, and generally contributing to society in ways that today get measured by traditional wealth and influence would be the path toward creating large amounts of personal data I believe.
It all comes down to what kind of gravitas you hold over other other people. The more people that want to see your data, the more valuable it is.
My two cents.. or should I say bytes. :-)
