As long as I can remember, the only “adult” aspiration that ever interested me was permanent migration to space. It’s actually a quite childish aspiration. When I was younger, what I found interesting and attractive about it was the combination of technology and pioneering, pretty much exactly what the industrial and military propaganda of the day wanted me to, er, grok.
When I got older, what was attractive was the possibility of leaving everyone else behind, but not unkindly, of being granted the privilege of a socially-approved escape from the dreary day-to-day responsibilities of life, such as taking the trash out or assuring other people, or your pets, that you love them.
None of that’s ever gonna happen.
