I also really miss the excitement and novelty I felt about things when I was younger. I look at my kids, how the smallest things are so fun and exciting for them. Now so much just feel like so much like "been there, done that". If If watch a movie, it all feels so predictable. If I travel, there doesn't seem like anything ever seems fresh or new anymore.
Perhaps because the world has become more similar. You can buy the same stuff anywhere in the world and the same chain stores are all over the world.
It also feels like I haven't quite followed up with expectations. When I visit the homes of parents of my kids playmates, their houses look so proper and serious. I feel I can't have people on visit because I still got half assembled 3D printers and robots in the living room. I feel like somebody who doesn't really want to grow up, but everybody is pushing me in that direction, even myself in the sense that I can't feel the same geek appreciating for technology. Technology feels less and less exciting and more like tools with a purpose. They have no intrinsic value as novelties or coolness.
Strangely I seem to care way more about people than technology. Do other ex-geeks/present geeks feel this way? Like tech stuff just isn't as interesting anymore. You get more interested in people? I think it is more fun to teach technology or write about it now, than actually doing it.
