I'm with you on that @legolas18. I see AI being used to handle the draping of cloth and hair, and doing the final render. Rather than spend huge time and power tracing a ba-zillion light rays, the AI engine would 'know' what stuff (materials etc) are supposed to look like, where shadows would go from the designated light, then just 'do it'. I'm flabbergasted even now in the early stages how good a job it does on fabrics like satin or sheers (something that Iray flubs at) and draping of materials (unlike the joke called D-Farce). Once it figures out that folks have at least, and only, five fingers, we'll be golden.
