no way man. the science of cryptography is a never ending battle of attrition. the ring signatures that monero uses will be broken some day. count on it. that doesnt mean we cant have a hell of a party while they hold and make some great use out of them before they are broken

that would be after BTC tho, since the crypto algos behind XMR are "safer", quite literally at the
elliptic curve (doesnt mean BTC isn't), btw I dont expect BTC to be broken any time soon (aka I doubt it will happen before quantum PCs are the norm).
also,
Probably it will be a while i agree. As an analogy, even if hammers are useless 100 years from now does that mean that everyone everywhere should stop manufacturing and using hammers right now? I think not. They are pretty damn useful right now, and will continue to be for some time so we should definitely get as much use out of them as we can so long as they are useful.
