Hmmm.. Aside from possible ethical concerns that this could raise, I don't know if having these bots are even enough to pacify paedo urges. It's one thing to argue aggressive nature and what can influence it into action. It's a whole different idea for sexual drives/urges. Sexual elements of humans are more needs than anything. Even after all the porn and simulated stimulation, the human body/psyche naturally craves/needs real sexual attachment. Including an emotional attachment that comes with it that bots may not be able to simulate. Top that off with the possible uncanny valley and there are doubts this could do much to pacify what is deeply rooted in humans. Honestly though we can only wait and see, if that is possible.
