Money doesn't grow in trees, and neither does Bitcoin., you need to be lucky to get a bitcoin lottery ticket and if you are lucky, you will definitely find a ball of diamonds in front of your house.
or some method of "brute" forcing was proven to be more effective than it should be (as technology progress's) then I would hope bitcoin could fork and build a wall against this. (Mainly thinking of quantum computing, but hey, maybe some powerful AI will be developed soon...)
I do not think that quantum computing and other things should be worried about in the short term, Bitcoin is safe even if quantum computers emerge and all these weaknesses need tens of years to prove their effectiveness, so we do not need a solid division now.
