“Why would the off-world colonists want troublesome, humanlike slaves rather than nice, efficient machines? It's simple. Machines don't suffer. They aren't capable of it. A machine doesn't know when it's being raped. There's no power relationship between you and a machine. That's been the U.N.'s whole pitch about the attractions of the off-world colonies all along. The big human thrill. For a replicant to suffer, to give its owners that whole master-slave energy, it has to have emotions.” SlaverySlavesBlade RunnerMachines And Man Book:Blade Runner 2: The Edge of Human Source: Blade Runner 2: The Edge of Human
