You don't think people will shag robots?
they already do. no, it's that I don't think people will create androids (n.b.
not robots, but synthetic humans) to do unpleasant tasks "off-world", wherever the fuck that's supposed to be anyway.
if the premise of the flick was that these androids were sex-workers & were fed up about their limited life-span & the natures of their existences, the whole thing would be dramatically improved.
the climactic speech of batty boy's would need a tweak.... "I've seen things you people wouldn't believe", that part could stay though.
