That he had the character of the adult entertainment industry mainsteading the production and development of these robots confounded me. It worked against his analogy, for one thing. Plus, it's just hard to buy. It's more likely that both new ventures would start producing them and that older, established companies like IBM with plenty of existing capital would make sub-brands. Think like how the big media companies keep their different channels apart, like how Viacom owns both MTV and Nickelodeon.
Also, he very carefully avoids mentioning all the good that the sexbots would do. He mentions that they would start producing child-themed robots. Well, that would provide an alternative for paedophiles, wouldn't it? Instead of society asking them to be celibate for a lifetime, it would ask them to settle for artificial partners only, which in the author's conceit would be superior in many ways to the 'real' thing. Also, UGH, slippery slope. The only people interested in "child and animal robots" would be people already
interested in those kinds of partners. I wouldn't be a bit surprised if the author believed that homosexuality was taught behaviour, caused by supernatural forces, or some such twaddle.
