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.

Not everything has to be a benefit.

For many of us it's not about some cost/benefit analysis, but passion and curiosity.

That's still following an objective perceived benefit: quenching a passion and satisfying curiosity.

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".

Sure, you're welcome to just stop examining thoughts at the surface level and not dig deeper. Other people here seem content with that. I'm not.

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.
