I know this conversation is very old and Holden has matured his outlook on the subject (see Open Philanthropy's grants to aging research, and Open Philanthropy's analysis of aging research, although still dismissive of SENS), but I still want to point out what I think were the mistakes he made here.
Holden didn't seem to get how different in scope the SENS' plan is from the kind of research that a single brilliant researcher can bring forward in the traditional way. SENS needs a plethora of different therapies that would require an entire NIA for themselves to be developed... and this would be enough only for the first phases of research and not for clinical trials. I don't get how he could be confused about this. Quoting Holden:
You [Aubrey] state that you have a high-expected-value plan that the academic world can't recognize the value of because of shortcomings such as "balkanisation" and risk aversion. I believe it may be true that the academic world has such problems to a degree; however, I also believe that there are a lot of extremely talented people in academia and that they often (though not necessarily always) find ways to move forward on promising work.
Also, I'm confused about why Holden put so much weight on Dario Amodei's opinion over Aubrey's. Dario is an AI researcher.
[...] And as my summary of our conversation shows, he [Dario] acknowledges that the world of biomedical research may have certain suboptimal incentives, but didn't seem to think that these issues are leaving specific, visible outstanding research programs on the table the way that your email implies. [...]
Thankfully, the Open Phil Holden obviously doesn't think this is the case.
A lot of the chatter about treating aging revolves around longevity, but it shouldn't. I'm all in favour of longevity, don't get me wrong, but it's not what gets me up in the morning: what does is health. I want people to be truly youthful, however long ago they were born: simple as that. The benefits of longevity per se to humanity may also be substantial, in the form of greater wisdom etc, but that would necessarily come about only very gradually (we won't have any 1000-year-old for at least 900 years whatever happens!), so it doesn't figure strongly in my calculations.
I have a hard time imagining being motivated more by health than longevity -- I would don a cyber-suit that keeps me alive but elderly for a hundred years to be rejuvenated later. However, the above is consistent with championing regenerative antiaging medicine rather than attempting to develop better cryonics.
(Better cryonics won't result in better health in the near term, so it's weaker on that front. But if the goal is to minimize the number of people who die and stay dead, it seems more likely to work in the near term than regenerative medicine.)

The way we (people in general) use the word "health" is based on a concept of the body as a well-defined entity. It becomes less well-defined when there is a technological solution that is as unobtrusive to use as part of your natural body; for example, a tooth with a filling works pretty much just as well as one that never had a cavity to begin with, so we don't think of it as an ongoing medical problem.

Well, for many people longevity is not valuable by itself, but only up to the exent that it enables them to enjoy more things they like. Poor health is a major quality of life destroyer, and indeed a significant number of severy ill people refuse treatment that would prolong their life without improving its quality. Some even actively commit suicide.
I suppose that people obsessed with immortaility fantasies find difficult to understand this.

That's sci-fi. There are no cyber-suits that keep you alive for a hundred years to be rejuvenated later. They don't exist now, and they are not expected to exist in the foreseable future.

Indeed. I doubt I would seek to extend my life under indefinitely poor conditions. I placed some limites on my illustration, e.g. elderly (not e.g. suffering intense and unremitting pain) and for a hundred years (not e.g. a thousand) for this reason.

It's not a difficult concept, so I don't know why you would think that about such people.

Archimedes once said that, given a long enough lever and a fulcrum to rest it on, he could move the world with his body... I suppose you think that's "sci-fi" as well? Lighten up! Thought experiments don't always have to be realistic to prove a point.
Holden seems sceptical, which seems appropriate to me. FWIW, I am not clear what function is being optimised in cases where where SENS gets recommended for funding. I figure that work aiming at prolonging lives is probably already over funded by the old-sick-friends-and-relatives phenomenon.
In the US (I'm not sure about in other countries), medical spending is skewed heavily towards people who are already very sick and often dying, while SENS is focused on delaying the onset of that state. Even if work on prolonging lives is over-funded, the funding that goes into it is likely being directed primarily to much less efficient ways of doing it.
Existing expenditure probably isn't effectively directed. However, SENS doesn't seem to be very much better. It's oriented towards biomedical gerontology. It seems pretty obvious that the way to produce potentially long-lived minds is to create them in a digital substrate - so that they can be copied and backed up. SENS seems to be pretty irrelevant to that project.
I visited the SENS lab in Mountain View in April of last year and was disappointed when no one I spoke to (Aubrey was absent, being his birthday of all coincidences) had heard of Givewell. So glad to see potential progress on them being considered.
But Holden's overview of the biomedical charity landscape is also concerning; perhaps one with the goal of defeating aging should in fact be focusing funds on closing the Valley of Death and/or reforming the drug approval process?
Givewell’s Holden Karnofsky, who has previously posted his thoughts on Givewell supporting SI/MIRI recently discussed the potential for Givewell to begin evaluating biomedical charities, in Givewell’s Yahoo Group. Someone suggested (as I have through less direct means) that they take a hard look at SENS Research Foundation, and then Aubrey de Grey appeared and began an interesting discussion with Holden.
The thread begins with Holden’s long initial post about Givewell’s stance on investigating and recommending biomedical charities, which is definitely worth the read for greater insight. The rest of the conversation is aggregated below for anyone else who can’t stomach Yahoo Groups’ interface.
Overall, Holden seems to agree with the goal of SENS, and interested in the details, but the conversation seems to have ended in October 2012 with Holden stating that he was waiting for Dario Amodei’s thoughts on SENS.
