I've long wondered when high quality CGI would become cheap enough to be used in porn, allowing any fantasies imaginable to be rendered realistically and without any actors being put in harm's way.
Of course, there are laws restricting some content from being created even digitally. (wide opening here for AdamSmith - oops, I mean opportunity for input - oh, never mind, he'll shove his oar in somehow ) For example, there are age-related laws for drawings and computer images, so I guess there could be laws written to prevent condom-free imagery even if no humans are at risk or even involved.
I've often imagined Tom-of-Finland-type characters, portrayed realistically and in color and 3D, creating any fantasy scene we can think of. Wonder how long till we see it?
