Question about Aubrey de Grey's "Ending Aging" theory.

so far from plausible that it commands no respect at all within the informed scientific community.

To explain to a layman why de Grey's programme falls into the realm of fantasy rather than science requires time, attention and the presentation of detailed background information. In addition, anyone who is tempted to do so is easily cast as a Luddite, an enemy of creativity and noble ambition, and someone whose prissy reluctance to confront de Grey's ideas might prevent us from living forever.

Each one of the specific proposals that comprise the SENS agenda is, at our present stage of ignorance, exceptionally optimistic. Therefore, by multiplying the probabilities of success, the claim that all of these proposals can be accomplished, although presented with confidence in de Grey's writings, seems nonsensical. Consequently, the idea that a research programme organized around the SENS agenda will not only retard ageing, but also reverse it—creating young people from old ones—and do so within our lifetime, is so far from plausible that it commands no respect at all within the informed scientific community.
