My own perspective (which I can already tell you'll likely disagree with) is that I want to live forever to remove the burden of having to choose only 1 to 2 more major experiences in my life (I'm 52). As an example I leaned Japanese. To do so I moved to Japan at 33. My experience there tells me if I want to learn Chinese and actually remember it I need to move to China for 6-8 years. Given I only have 20-30 years left and probably less in pure freedom of movement (meaning my body will get old and limit where I live and what I can do), then ATM I only get to choose 1, 2 or 3 more major things to do with my life. If I could live forever I'd choose to do all of them knowing I have plenty of time left. I'd spend 8+ years in China. Maybe 6+ years in Germany and 6+ in France and 6+ in Italy and 6+ in Spain and a few in South American countries and then others. I'd go back to school and learn various topics spending several years in each. I don't agree with your assertion wanting to live a long long time has anything to do with ego. People used to only live to an average of 30. Today I saw a program on Japanese TV showing they have 60000 people over 100 years old. They showed several having productive lives, some were still running stores. One was a hairdresser. She still loved meeting and talking to people while cutting their hair. She was 102. The current stats say that 60k number will be 120k in only 3 more years. What does the fact the people in the past died have anything to do with anything? People in the past died of all kinds of diseases so people now are ego driven to use the tech that prevents those diseases? I also see no relation to empathy. In fact the older I get the more empathy I seem to have.
