I feel like the younger folk tend to re-invent ideas that have come and gone, and don't do enough research to see what has come before. They spin their wheels figuring out things that us older folk already know. Sure, they do it with newer toolkits than I know, and that is why I keep up on HN - because the newer technologies are where the younger crowd can teach me something.
But I don't feel lost in the culture... I feel disinterested in it.
I also think that being older, with a family, and a full life outside of work, I'm not interested in pursuing wealth the same way that young people are. I have a nest egg, I have a good salary, I also have a wife, children, a small farm that we run, mountains, deserts and oceans to explore, stars to look at, etc.
I am no longer 23 and trying to establish my life. I am 43, have built a life that works for me, and am far more concerned with raising my children than with raising my wealth. To me wealth is binary - you have enough to live your life, or you do not. At the moment, I do.
So can I hack life to get more out of it? I think I already have.
