Of the rather few explicitly religious commentaries on nanotech so far, some have focused on issues that could have been raised by secular voices: safety, commercial control and accountability, and responsible application. Nanotech scientists have long sought to rescue their discipline's public image from the vocal but fringe spokespersons such as Eric Drexler and Ray Kurzweil, who have painted a fantastic picture of tiny robots patching up our cells and extending our longevity. Kurzweil has suggested nanotech will help guide us to a moment he calls the Singularity: a convergence of growing computer power and medical capability that will transform us into disembodied immortals. But the transhumanism question isn't unique to nanotech it's part of a wider debate about the ethics of human enhancement and modification.
