Do you know how are overpopulation and transhumanism correlated with each other?

My guess is that by fusing human and machine (or, for that matter, humand and AI), they can’t have kids, or they’ll have outgrown that functionality. What do you guys think? Let me know! I’m gonna tap the collective (fluther’s ad), or, should I say, I’m gonna tap the collective UN(maybe not)consciousness to bring it to the conscious. ;-p
