It is inevitable that aging will be "solved" at some point. It's going to disrupt society as much as the emergence of AI, and we as a species are not mature enough to deal with either. Let us hope we navigate these waters carefully.
I forget the exact number but testing that works on mice only is successful at human level trials around 1% of the time. Obviously it's still impressive and shows it is possible. I'm just skeptical we will see anything significant in our lifetimes with this other than HGH or stuff that just helps men fight the negative effects of old age.
I may be in the minority but I actually think life makes sense to be finite, especially if it prevents new lives from entering our world.
I have a sister who has her own lab and I am pretty sure that success rate is a lot higher then 1 percent of the time. I know because lab mice is big business. She just does not go to the local pet smart and by mice she gets them from labs that produce mice. These mice cost serious cash because they have specific traits to them. I think if researchers where achieving 1 percent success rate they would use other animal types for research. But about aging I would not get to excited already because there is a lot of issues tied to aging and from the looks of it they are more likely trying to market an anti aging pill. I don't know anything about the science but I do know eventually they will figure out something.
500 years? thats a long ass time to go without being hit by a car or all the other day to day shit that kills people.
