It might be environmentally sound to become disembodied minds. A brain in a VR environment has lower energy and nutrition requirements. Bodies could be remote controlled when needed. (Incidentally, this is the premise of Cortex Command... but then of course the brains have to build battle robots and blow hit up, because it is a video game after all.)
I think it's inevitable that we'll turn into something else, because we're already well on our way. A car, cellphone or computer mouse can be a seemingly telepathically controlled appendage of our bodies. It's really quite remarkable how good the human brain is at accepting augmentation.
The conclusion of that article made me uneasy.
