Barring quantum computers, is Monero immune from cryptographic breaks?
Quoting gmaxwell's statement on bitcoin's cryptography strength:

But for me as a long term holder, it would just be another blip on the radar.
Or, perhaps, you quietly lose 100% of your position over a period of months while attackers target high value slow moving txouts and move them and cash out long before anyone realizes there is a break.
A second preimage vulnerability would allow forging your signatures... even if you noticed people would just think you and other people complaining got hacked.
This kind of break isn't likely by any means, but it is not outside the bounds of plausibility. You are not immune from cryptographic breaks.
