I see a parallel to our immune system. One of the most complex pieces of machinery in our bodies has the sole function to keep us from getting overrun and taken over by "hackers". When I look at nature as an example I see a way to more complexity in the things we create - because they are not actually completely "designed", instead we let laws of nature govern how they develop, so I think it's not too far-fetched to look at existing nature-designed systems for guidance on predictions about the future of man-made systems.
I just have to say, thank goodness for Moore's Law. Without it, we would never have so many wasted cycles![0]
[0] Not saying you're wasting, but the fact that we have to jump through sooo many hoops to stop all this crap is just disgusting.
