Here's a random thought. If we were to predict what social and cultural changes might accompany the Singularity, we might find ourselves describing people "speeding up" in terms of their interactions with the environment. We might theorize that as the pace of technological change increased, people would become increasingly bored with environments and activities that were out of pace with such change. This might be particularly apparent in the young, who would be most acclimatized to rapid change--they would know nothing else--and least able to control their need for stimulation.
Along these lines, we might theorize that environmental influences could have a physical effect on children. As parents became increasingly stressed by the rapid pace of technological change, certain hormones and other biomolecules might alter gene expression during gestation. Thus children might be born sensitized to rapid change, wired for it in their very DNA. We know of several such feedback effects in nature.
All of this leads to some interesting speculation. There is much debate about why rates of ADHD appear to be increasing. It may simply be increased diagnosis, but there do appear to be some actual neurological differences involved. So we can ask: Is ADHD some sort of reaction to the Singularity? And if so, might rates of ADHD provide some sort of barometer of progress? Might they have historically risen and fallen with major technological revolutions, such as the rise of the World Wide Web?
As I said, just a random thought. I'd keep going with it, but I've grown bored.
