Define "curing". Is it giving some decent percentage of people an extra 10, 20, maybe even 30 years of reasonably healthy life, compared to what they have today? Or is it making people live forever? The first objective, as challenging as it is, sounds a lot more plausible than the second. If we ever achieve either, I'm sure the first will be reached long before the second is.
By a literal definition of "curing", only the second is a "cure". But the first would still be an amazing achievement, and is probably a prerequisite to ever being able to achieve the second.
You might be able to cure dying without curing age related degeneration of the body. Migrating minds outside of the body might be possible. To me it seems quite likely.
