Humans infected with computer viruses; what are your thought?

Came across this article on Gizmodo today.

What are your thoughts on this subject? How big of an issue could this be in the future? How far will it go? What are it’s possibilities? Are we headed toward a zombie apocalypse? How can we prevent such hazards? Will people be able to hack into our bodies the same way they do with computers?

Tell us your imaginative, far-out scenario that this could generate.

Any other thoughts?
