Science

I filled it out, but let's discuss in the comments because filling out a one sided form isn't as fun as being able to have a multi sided discussion.

I personally find biological immortality super appealing. Despite the word "immortality" in it, it actually just means you can live as long as you want, which takes away many of the downsides to immortality that often get discussed. Since I'm not religious, I don't believe in any kind of afterlife, so scientific advancement letting me live longer is the only way I can avoid death (which I'm afraid of). And more than just avoiding death, I want to avoid being a frail senior whose quality of life is severely diminished.

That said, for me, I ranked the positive advancements with the disease prevention, medical advancement, and QoL above simply extending human life. I think these all do of course go hand in hand. But fewer people dying young is better than fewer people dying old. Dying young is really tragic, because there's so much of life you won't have experienced. Similarly, the big issue with growing old is age related diseases, which impact your quality of life. At a certain point, Alzheimer's and dementia seem worse than death. I feel conflicted because I don't want to die but if I had a disease like one of those, it seems like I'd no longer be myself and it's unlikely there's any hope for recovery before the disease eventually kills me. There's also the fear that perhaps I would be myself, but feel trapped inside a body, constantly confused and afraid by what's going on, which sounds horrible.

On the negative impact side, by far my biggest concern is imbalance in access to this immortality. My fear is that regular folks (including myself) won't have access but billionaires will. That's worse than not having immortality, since billionaires are generally terrible people and not who we want living longer. Overpopulation is a bit of a concern, but one that I think we can eventually solve. e.g., with social changes to expectations about having kids, automation improvements to reduce our need for people to work, and eventually moving beyond just living on the surface of earth. Wealthy nations already have a declining birth rate, anyway. As well, I'm a bit skeptical about true biological immortality, as opposed to, say, extending life on earth for a good chunk of time, but eventually moving to a digital afterlife, where overpopulation is less of a concern.

I didn't know how to answer the regulation question. I think most things need some level of regulation, but the options were "strict regulation" vs "unrestricted", neither which sound right to me. As well, regulation would likely be completely situational. e.g., obviously safety is a vital part of any form of medical treatment. We shouldn't be reducing any existing regulation there. But I certainly don't want research into the area to be unnecessarily held back. For a large part, I see this as no different from researching a cure for any other disease. Aging can be viewed as a disease.
