I could consent to have you shoot me, but it will still injure and possibly kill me. A child or their parent could consent to being shown graphic sexual or violent imagery, but it would still cause psychological damage. Rape is not theft but assault, and society does not allow such harm to be perpetrated just because someone thought they could handle it.
Yesterday I sat down with Lukeprog for a few hours and we produced this ten-page interview for the Singularity Institute blog. This interview contains information about the Singularity Institute's technical research program and recent staff changes that hasn't been announced anywhere else! We hope you find it informative.
