Don't see the connection.
I don't understand how much clearer I can get. We need robots for labor. We don't need robots for sex. They don't go hand-in-hand and saying no to one isn't saying no to the other.
No not really. You can't fuck a tractor or forklift, can you? The creation of robots for sex is an entirely new and degenerate branch of robotics and it is entirely natural for a work-purposed humanoid robot to look just like this:
Yes it will. Degenerate values destroy societies.
Yes, pulling ahead in productivity by using robots for labor. This has nothing to do with sex bots.
Don't see the connection.
I have no objections to robots that replace human labor; this isn't about that at all.
I don't know what a best scenario for humanity even means because humanity is divided in in its goals. But from a Chinese perspective, no. I would be wonderful if America or Israel led in the sex bots industry (of course, China will lead in the labor bots industry) and the plummetted the fertility rates in the West while China banned them from import.
But this is all a bit premature because it is assuming that they are even capable of replacing a human sexual partner, which they are currently not and far from it. Like I said above, they may just be limited to use for the incels and losers to keep them from going postal from rejection rage and be kept out of the mainstream from stigma.
