Unfortunately, no, this is pure wishful thinking. Using life expectancy is a misleading argument, and I believe intentionally so. Life expectancy is a function of early mortality. Longevity is the average age at death of people who die only of old age, and it doesn't vary much and hasn't for thousands of years. https://en.m.wikipedia.org/wiki/Longevity Ray Kurzweil and Aubrey De Grey are playing on the hopes and fear…
The ongoing increase in life expectancy in developed countries is associated with changes in the shape of the survival curve. These changes can be characterized by two main, distinct components: (i) the decline in premature mortality, i.e., the concentration of deaths around some high value of the mean age at death, also termed rectangularization of the survival curve; and (ii) the increase of this mean age at death, i.e., longevity, which directly reflects the reduction of mortality at advanced ages. Several recent observations suggest that both mechanisms are simultaneously taking place. ... We illustrate the method with the evolution of the Swiss mortality data between 1876 and 2006. Using our approach, we are able to say that the increase in longevity and rectangularization explain each about 50% of the secular increase of life expectancy.

This history has happened without anyone trying deliberately to target and treat the causes of aging - all gains in longevity have been incidental. The difference between the past and the future at this point is that now the research community is just starting to develop therapies that do in fact target and repair the causes of aging. Future results will reflect that change of focus.
