Nuclear scientists lost their innocence when we used the atom bomb for the very first time. So we could argue computer scientists lost their innocence in 2009 when we started using malware as an offensive attack weapon.
There is no need to have your computer online 24 hours (a day) as a target of an attack when you are sleeping or away from your computer.
Everybody was hoping they would get the patch out before a major attack would start. Now it looks like they are succeeding in doing just that. Well done.
There might be no attack at all. As everybody knows about the attack, the virus writer may lay low and attack at a later date. The ISPs involved can actively block malicious postings. It's more likely the attacker will lay low or be blocked, rather than succeed.
