Unless you're really special nothing you think of is original. I'm not saying you're not special though. :)

Hahaha thanks. I read somewhere that at the same time you think of a grand new idea, 10 people somewhere in the world will also have the same idea. I doubt that's always true, but it's pretty amazing nonetheless.

Heh, that is depressingly likely given the numbers. There must be a german word for the appreciation of a clever/accurate but depressing idea.

Twas ever thus. Look at how many great inventions and discoveries throughout history were arrived at independently and then argued for the bragging rights, before it became such a priority to share your ideas. Calculus and television spring immediately to mind, but there are many others.

Weltschmerz comes close.

That is an excellent word and concept, thank you.

But it lacks the appreciation of how interesting the depressing observation is.

Weltschmerzfreude seems like it's just a contradiction (also I know almost no german at all so it's likely just gibberish) but it doesn't sound bad.
