This comment upsets me.

How pretentious to define what people should do with their lives and how long they should live based on some loosely defined "progress". Society doesn't have a moral obligation of pumping out geniuses. People live because that's a natural right.

Besides, not many things in life are more valuable than sitting down and having a chat with someone 70, 80, 90 years old. It's wisdom you won't find on Google.

I'm not saying what people should do with their lives. I'm pointing out a counterpoint to the usual cheerleading about life extension. It'll be a world in which things change more slowly. Definitely in terms of social progress, but potentially also in terms of scientific progress.
