Why a collision? Abuse it where it is being used. Infect the chain of certificates that guarantees that the hash you are checking is actually the one you want. Send a million legit documents with bad hashes, so that the forged one looks like another legit one. Infect the library that calculates hashes so that these specific documents have a special hardcoded hash.

replyWell, if you are that picky, then you will have to wait. MD5 was created in 1991, the first collision was found in 2004.
replyYou want to pick a date and make a bet?
replyYou are the one discarding every date. I'll take the opposite bet: it will eventually happen, on some date.
replyI haven't discarded any date. Pick one, and an amount to bet!
