It's definitely an interesting exercise to find out, to the best of our knowledge, how we will have evolved, appearance-wise. However, predicting anything that far out is rather moot. For all we know, humans may give up being constrained in a biological body, and move to a different form of reality. Or there may be an unexpected mass extinction event. Or our perception of what is beautiful may change drastically. Google glass and miniature cochlear implants will still be used 20,000 years in the future? Come on. This is like neanderthals saying the modern humans will have super big and long spears. I'm pretty sure by then, if we still have a brain in any form recognizable to us today, it'd probably have that capability built-in (assuming whatever value a google glass and cochlear implant provide would still be valued by people/society (if any) in the future...I said if any because the organization of humanity may change drastically in that time frame. No more nation-states, no more individuals, individual consciousness fluidly join and detach from others, big organizations form and crumble in nanoseconds for a fleeting purpose, who knows. Would there still be individuals even?) Anyhow, I digressed. Still fun to speculate, I say.
