At the risk of sounding callous, I don’t care about any “cycles.” In the end, boredom is a problem with many potential solutions- we don’t need death specifically. Even in the worst-case, where we’ve “done everything,” couldn’t we develop a way to modify or suppress our own memories to make experiences “fresh” again?

Arguments like these, where the problem created is so much milder than the one that’s solved, feel like philosophical sour grapes. We are mortal, and without extreme technological advances, we’re going to stay that way, so we come up with excuses as to why it’s ostensibly a good thing, so we don’t have to confront the problem.
