Better security is always good but it will, like everything else, end up being like the radar detector industry. When the radar detector companies build a better unit the companies that make the radar units will come up with another way or beating it so the coppers can book yet more people.
Relating this to computers... Security protocols are doors with locks that are meant to keep h4x0rs out... All it takes is the inventor(s) of IPV6 to say "this is fool-proof and totally secure" and someone who knows what they are doing will work their way around it. There's an old saying that locks only keep honest people out. It applies to computers as much as one's front door.
