Living long enough to see everything else die while pseudo-immortals try to fight entropy-particularly with the much worse coming consequences of human civilization borrowing heavily against the ecosystem- is a hell I don’t think I would want to see. Like the author, I’m not opposed to extending a bit, but… I suppose that’s a slippery slope. Today “just a little longer” seems reasonable, and then it will be just a little bit longer, and then a little bit longer after that. I suppose at some point after that you risk becoming little more than your dwindling ego, something of a lich lord or revenant jealously draining the world of life because you’re too afraid to admit: you don’t matter (no one does in the grand scheme of things) and the universe wasn’t designed for immortality or to appease your ego. In the more practical and nearer term, I fear life extension will be more a matter of trading quality of life simply to avoid dying, a form of life support. Doesn’t sound good to me.
