I mean, are you miserable? Or are you just using the wrong expectation for being happy? Because overly unrealistic expectations can make any ever-present annoyance, like the day to day dealings of entropy and decay, an inescapable hell.
I think therein lies why we continue to do the "same thing". It's not so clear what would make you less miserable. I know I wish it were that easy for me.
I mean the same things that make it miserable likely add resistance to change.
Not having a destination, plan, or means? Yeah, things'd be different living on the street but I think it'd still be miserable (in a different way).
On long enough timelines it doesn't matter at all since universes probably don't last forever, or at least can't support stuff, especially thinking or working stuff
Yeah, with how things are going now I don't think humanity will have much more than maybe a small moon colony (if that), but just to be clear that last bit in my comment is a quote, Carl from ATHF.
Although I'd say I don't need a long timeline for things to not matter, and that's kinda the issue. Or a result of all the issues.
