"Does anyone seriously think we will grow old and die 500 years from now?" Absolutely. Here's a few reasons why I think that way: A)Even if we somehow solve the problem of aging, some people (quite possibly many or even most) will still choose to live a "natural" life for any number of reasons. B)History suggests that we will not continue our current rate of progress indefinitely. Who knows how long it may take to recover from the inevitable disruptions. C)I suspect that, like cancer or practical flying cars, aging is a harder problem than we think it is. Just because we can envision the end result does not mean we can achieve it. D)Based on current medical trends, any effective anti-aging treatment is likely to be so expensive that the vast majority of people will not be able to afford it. E)In the end, entropy always wins. My apologies for all the pessimism. :)
