I think it depends rather highly on how the causes of death are impacted, and the nature of the extension.

If it's what I think it is, it's more or less stretching out the body's decay, rather than just adding a number of years in a specific physical state. So people that randomly die at any point after 50 are still going to, rather than living forever. That's an issue for a far, far improved version of this treatment, if it's ever possible.

Going by the 7% figure in the study, 7 years assuming a lifespan of 100 would figure into maybe 3 or 4 at an optimal age if applied early enough, and wouldn't really impact average society beyond a slight increase across the board. It's not exactly an immediate exponential increase, though it could snowball into one.

Then again, with the average age of parents steadily rising, it might not seriously impact birthrate at all.
