There are many other factors that determine aging besides telomere shortening, but if this is able to become controllable for humans, it could very well mean a dramatic increase in life span, or even the end of aging.
But it's not actually the fountain of youth, per se, as the other factors involved in aging hasn't stopped. Things like arterial clogging and compiling tissue damage will still shorten lifespans, as well as things like cancer and diseases.
So for true indefinite lifespan to be reached, we'll also need to catch up on nanoscale medicine, stem cell manipulation, and cancer prevention/cure.
I agree; this breakthrough, amazing though it may be, is not an absolute solution to aging in humans. Any uses to be found for humans in it wont be developed for a very long time as well. It's great and everything, but I wouldn't get my hopes up for immortality based on it.
I had heard about some other research being done recently that sounds pretty similar to this, having to do with extending telomeres to try and repair certain causes of blindness. It would seem that there is a promising future in it.
I really don't think they should have said, "reversed aging." It's not actually what they are doing. It's repairing and impeding damage associated with aging, which while sounding like the same thing, isn't. So it's leading people to get the wrong idea about what this could actually do.
Besides, until we can cure cancer, everyone will eventually die. The world is carcinogenic.
