This technology will not reverse aging. It might however reverse some aspects of aging, and quality as life extension. However, one could argue that living longer means people may live until aging can really be reversed, so its a good first step. Resveratrol for example has been a hot research topic for quite some time. It reverses, halts or modifies some aspects of aging. Its similar in impact to calorie restriction, which is a long recognised way of slowing aging.
One thing I would want to see in aging reversal is telemere restoration. Any real anti-aging would have to do that at a minimum, as well as switch on or off specific genes which is what they are looking at. Now its entirely possible that they can restore telemeres using these methods, but they have yet to say so or provide evidence.
Aging reversal would also require some way to restore DNA, both in the cell nucleus and the mitochondria.
