I know there is a shortcut to this but for this to be true you need a constant rate of 1 death in 1415.78389 per year.
1 / (1 - 10 ^ ((log .5) / 981)) = 1415.78389 so (1-1/1415.78389) ^ (1000-19) = .5
When my intro to genetics teacher in college explained to us how aging in cells worked, he told us that one of his professors had explained to him that a "cure" for aging was about 10 years away. But that had been more than ten years earlier. My professor said that he had recently talked to that same professor again. The new ETA: about 10 years. This is one of those problems that seems easy to solve in principle, but…
I think part of it might be that evolution only cares about how successful you are in passing on your genes. Why do salmon die after mating (its due to exhaustion)? There isn't really any reason they have too, but they successfully passed on there genes so there is little evolutionary pressure on what happens afterward. I think it is the same for aging. There isn't really a reason for aging, it just happens because t…
Earlier quoted context omitted.
He's looking for cures to issues that are real problems. If you fix any of the problems, even partially, they show great promise for helping older people to be decrepit, even if they don't actually extend lifespan. His hope is curing these types of damage will cause humans to functionally stop aging, but curing these types of damage are useful in and of themselves : Cell loss, tissue atrophy Nuclear [epi]mutations Mu…
In fact, the SENS foundation is ignoring some of those - because medical research is already attacking them as problems in their own right.
Just going based on the title here. But if we let people live to 1000, that will deny many people the right to have children. The long term consequences of such a change could be a drastic slow down in technological innovation as the super-elderly are able to accumulate vast sums of wealth. Just think of the advantage you'd have as a 500 y/o over a 25 y/o.
Why is childbirth a right? Would you accept a trade of a parent's life for a child's life, perhaps with a time delay? There's also several financial methods that could be used to prevent undesirable wealth accumulation.

I doubt that we'll ever find a "reason" for aging. It's the result of an imperfectly optimized biological system - after all, humans are the result of one great big evolutionary algorithm. We've proven time and again that those run exponentially and are not perfectly accurate, especially in the presence of a dynamic environment.
How come that chain hasn't failed?
Basically, you're just rephrasing the "aging through accumulation of errors" hypothesis. The problem is, errors should accumulate along the chain mentioned above, too. Yet they don't.

Hypothetical populations that didn't age and die would have killed themselves off due to lack of food.

So we're perpetually closer to curing aging than we are to energy-positive fusion? If only they were reversed, we'd be able to support the population explosion in millenarians before they got here...
See, if you predict a breakthrough in five years and are then awarded a seven-year grant, you're setting yourself up for a lot of embarrassment when it comes time to apply for a renewal.
The future is in the future, and until you're absolutely certain of success it's important to keep it there. ;)

[1] that's the predicted future. The actual future isn't in the future at all. It arrives every day, without warning, as a fait accompli. There's no money in predicting the near future: you must either predict the far future, or make the near future.

The "reason" for aging seems almost self-evident to me. The goal is to pass on [mutated] genetic information. Post-reproduction, you're simply a drag on local resources. Hypothetical populations that didn't age and die would have killed themselves off due to lack of food.
