According to an acquaintance,

The knowledge that I seek can only bring other people misfortune - it has, for the most part, no point nor purpose.

What a rude comment. The knowledge that I obtained bore fruit.

It was useful to some extent in the war - though I don't know if it would be enough to make you smile.

In other words, there is not a single piece of useless knowledge, and further more, I am entitled to obtain said knowledge.

That's how the story goes.

I'm interested, so I'll try it. That's all there is to it.
