I don't quite understand why You think those two in particular are good examples of failed education.
In my opinion examples of failures from lack of education would be something like users running e-mail attachments, users not being able to properly spot a phishing mail, users being victims of social engineering and stuff like that.
The blaster and Sasser worms were more caused by vulnerable services. Read: defective software rather than defective users.
Please explain why You see it as a result of failed education.
Or maybe what You are saying is that if users *today* still keep getting hit by these, it is an example of failed education. In that sense, I would agree.
