There are infinite problems.
No matter how much we understand about the world, our knowledge will remain incomplete.
There are always exceptions to the rule. Always holes in the theory. Always new discoveries on the horizon that will flip our current assumptions upside down.
Why is this important?
Because it means that reality is an open-ended problem.
It cannot be solved ahead of time. There's no optimal strategy to be found. To do anything, we need to risk everything.
But it also seems like there's a deeper certainty.
A set of emergent properties that arise from our continual expansion of knowledge.
Fundamentals that lie outside the realm of understanding, but that are necessary for such understanding to survive.
Constraints that reduce the world to solvable problems, so that we can move forward.
Ideas that demand the subjugation of everything else, but in return, promise something infinitely better.
Such principles could invalidate everything we've just discussed.
Maybe that's why they're necessary.
