[Ages ago, as a graduate student, I "wasted" my time (when I should have been finishing my thesis) reading capital theory, including the more "heterodox" stuff. My memory is pretty hazy, but I still think about the old questions occasionally. There's nothing really new here for economists familiar with "dated goods".]
1. Suppose I know about a technology that lets me convert 100 apples into 105 bananas. Should we count those extra 5 bananas as part of my income? Of course not. You can't add (or subtract) apples and oranges bananas. They are two different goods. They don't taste the same.
