Productivity is an industrial term.
It even derives from the very industrial concept of “production.”
The thing is, production may be valuable to society writ large, but it doesn’t really speak to you as an individual.
I mean, a robot can be productive, but all that is just programming. That’s like saying “calculators are good at math.”
Someday, as far as we know, it will be the end.
So you’ve got to do everything you want to do now.
You can’t wait to the end to start.
