we see that the computer crime landscape is substantially the same as it is today.

The fact is, evil is in the heart of man. People are going to use whatever technology is available to do what they're going to do. Criminals use cars, air travel, and telephones every day. We can certainly close off certain avenues of technological attack, but as long as there is a motive, people are going find the opportunity to commit crimes.
