that there are exponentially-accelerating advancements unfolding is unquestionable... however, it also may be quite possible that the vision Kurzweil and company have for what "the Singularity" is and may look like may be quite a bit different than how they present.
keep in mind, many predictive projections are based on our current levels of understanding and frames of reference. some of the most significant leaps to come, we may not even yet be able to fathom in the context of any sort of reference available now.
chances are, things will unfold alot differently than envisioned - especially in a new realm of quantum computing - and integrating A.I. into technologies functioning in quantum consciousness states, rather than physical technology alone as most are viewing A.I. as computer-based... ;-)
