I think Borges is correct in principle when he posits true immortality as a curse, but I think he's absolutely wrong that someone would get bored of life within a couple thousand years. I would bet a considerable sum that it would take me five thousand years minimum to get sick of living if my body remained in decent condition, and I would probably make it to ten if people kept making music and food
annoying the shit out of my fellow vampires by responding “only boring people get bored” every time they express existential ennui
