There's a big difference between keeping someone alive and extending their life beyond what's biological natural. Just because someone can walk away from a horrific car crash thanks to modern medicine - doesn't mean we can live forever.
Not yet. But is on the way.
Maybe saying that some of us will live 1000 years its a little too positive. I think his point is that we are advancing exponentially fast, and soon we will live much more than we expect today (in our lifetime, I mean). But in 3300? We will be immortals by then,merged with machines and who knows what else. Talk to your grandfather, can you notice the number of things that have changed?
EDIT: check out the 2nd link, that is today! Not sci-fi... Do you remember when people talked about nanobots working inside you to keep you healthy? That was a few years ago, now scientists have nanobots working inside mice. In 5 years they will be inside you ;D
EDIT2: but the point is that emperor cant be dying! Its a scam or a bait for something!
