What I mean is that by 31DEC15 no exchanges, wallets, point of sales, or any other Bitcoin transaction gets hacked, attacked, goxxed, or unintentionally burned. I know we can't stop people from being scammed, nor can we force people to practice good backup discipline. Those will be for 2017. But for now let's make sure that in 2016 there will be no more hacks.
Multisig will help a lot.
When wallets were first introduced your .dat file was saved in text forum, unencrypted. Encrypting that helped a lot. Multisig will help when it comes to keeping your keys safe.
