You gilded the tip of [i.e., added a valuable new link to] a long chain [of valuable independent links each created by some individual or small group of individuals] of human creation that the world was lucky enough to be handed, and now the world thinks you fucking owed it that? That's absurdly arrogant.

If you create a thing in the world that did not exist before, and other people find it valuable, why should you not be able to reap some of that value? Why is the world more entitled to the thing you made, the insight you had, and the work you put in, than you are?
