You have an implicit assumption that the benefit of learning information always justifies the effort and time spent on learning it. I don't think that's a given or true.
Now you’re moving the goal posts. You argued that writings from the past are worthless; I pointed out that they have great historical value. Cost-benefit analysis is beside the point. But we’re both here writing comments in a Hacker News thread so the option value of our time can’t be all that high.
It's following a passion, but hardly an "objectively perceived benefit".
Except in the sense that everything is a benefit (including shooting heroin, where the benefit is the high, and so on) where the term becomes meaningless. But even so, it still wouldn't be "objectively perceived". More like "subjectively pursued and felt".
