The first is rather mundane: I get the impression that ‘turning 18′ used to be a big right of passage that marked one as having become an adult. I feel like the ‘real’ right of passage is now college graduation. I really feel like an adult now that I’m supporting myself entirely on my own in a new state.
The second is a bit more profound: Many problems that people are trying to solve have solutions that tend towards simulations of the entire world. More on this one later. Maybe.
