There's no Omega, so why not take the nanoslice of power that's readily available, in addition to whatever you can get by trying for more? It appears to me that doing both maximizes the expected payoff in all probable contexts.
Opportunity costs, in short. If you're giving up more resource-equivalent time on that nanoslice of power than you expect it to return in dividends, it's not worth your effort -- and depending on how you do the counting, a lot of prominent examples return so little that it doesn't take much time outlay for this to be the case.
In the specific case of voting, though, there are signaling effects to consider that might overwhelm its conventional dividends. Jurisdictions like Australia where voting is mandatory also change the incentive landscape.
Don't let your minds be killed, but I was wondering if there were any existential risk angles to the coming American election (if there isn't, then I'll simply retreat to raw, enjoyable and empty tribalism).
I can see three (quite tenuous) angles:
But these all seem weak factors. So, less wronger, let me know: are the things I should care about in the election, or can I just lie back and enjoy it as a piece of interesting theatre?
