The way I see it, when we’re talking about non-me humans, the vast majority of them will be replaced with people I probably like roughly the same amount, so my preference for longevity in general is mild.
Am I reading this incorrectly or are you saying that you don’t care about your friends and loved ones dying?
There’s at least two currently ongoing clinical trials with an explicit goal of slowing aging in humans (TAME and PEARL), that’s just the most salient example. At some point I’ll definitely make a post with a detailed answer to the question of “what can I do”. As for the problem not being solvable in principle, I don’t believe I’ve ever seen an argument for this which didn’t involve a horrendous strawman or quasi-religion of some sort.
I personally believe exactly the right kind of advocacy may be extremely effective, but that’s really a story for a post. Otherwise yeah, AGI is probably higher impact for those who can and want to work there. However, in my observation the majority of rationalists do not in fact work in AGI, and imao life extension and adjacent areas have a much wider range of opportunities and so could be a good fit for many of those people.
