Not really. The dummy features have a practical purpose to help the silicon deal with stress. Its similar to the ridges and lines that car manufacturers are putting on the panels of new cars. The metal is so thin on these panels that they have to put ridges to stop them from bending. The same thing has happened with processors. We have reached a point where the chips are so small that similar ridges have to incorporated to even out stress within the chip.

You might be dismissing the point too soon. To the lay-person, junk DNA looks like as useless a feature as a ridge in a door panel, or dummy pathways on a chip. To an expert auto-maker, the purpose of the panel ridges is obvious, structural rigidity. To an expert chip-maker, the purpose of dummy pathway is obvious. To Our Holy Creator Who Art in Heaven (or whomever you wish to credit our creation), it is possible that our junk DNA has a very obvious purpose that we have yet to divine.

Junk DNA does (or did, in many cases) have a purpose. Its just that any DNA which we don't understand the purpose for is labeled as junk. That definitely doesn't mean it doesn't do anything or that its useless.

Greg Bear's Darwin's Radio is an interesting scifi take on the idea that some junk DNA could be just one evolutionary step away from being activated.

Darwins Radio was a great read but I don't find the idea of ready made features for future use in our DNA very plausible.

He spins an amazing yarn around it though, and plenty of the social consequences are very believable.

Junk DNA could be protecting the useful DNA, so I can see an analogy.

Very good point!
