If we were to stop all deaths — every single one around the globe — right now, we would add about 150,000 people to our planet each day. That would be 55 million people each year. That might sound like a lot, but it would be less than a single percentage point. At that rate, we would add a billion people to our ranks every eighteen years, which is still considerably slower than the rate at which the last few billion people have come along and easily countered by the global decline in family sizes.
It's still an increase, but it's not the sort of exponential growth many people fret about when they first encounter the idea of slowing aging.
Recall, these calculations are what we'd face if we ended all deaths right away. And although I'm very optimistic about the prospects for prolonged vitality, I'm not that optimistic. I don't know any reputable scientist who is.

As cloning beautifully proves, our cells retain their youthful digital information even when we are old. To become young again, we just need to find some polish to remove the scratches.
