This is a genuine question. Why do bitcoiners have so much faith that quantum computing won’t break the cryptography that secures bitcoin?

I don’t know how likely it is, but it feels like the chance is higher than 0% and lower than 100%. There’s a real non-zero chance that the current implementation of bitcoin won’t work in a decade. Doesn’t that give maxis cause for concern?

Maybe there is a good answer. I see lots of discussion about fiat, emissions around mining, privacy, taxes, and tons about regulation. But isn’t quantum computing an existential risk?

And if it is a real, potentially small, but fundamental risk, wouldn’t the prudent thing to do would be to diversify risk?
