These broad strokes are always the result of poor reporting extrapolated to all humans. See also: escalation of porn use.
In all of these "___ makes people ___," there are a minority of people for which it's true. The media just presents it backward, as though most people are this way.
The question then becomes, do we care. Let a maladjusted 12-year old boy play with a sexbot for the next few years and they will come to some deeply-flawed conclusions about how sexual interactions and healthy human relationships work. If he's distracted and banging away at a flashlight, that's one less competitor for me on the dating market.
Where does that end though? What happens when he wakes up, realizes he's been duped, and goes looking for retribution against someone? It won't be PornHub; they're an ephemeral concept. It won't be me either; I never did him wrong or denied him anything. The victim is more likely to be our wives and daughters-- the objects of his envy.
Entertainment is supposed to be a distraction-- maybe you drag out the sexbot after an unsuccessful night of trying to hook up. But that's not how these things get used. People clearly spend 8-12 hours at a time with these things and form parasocial relationships with them instead of forging actual human connections. Most of us don't need the handholding to be told this isn't going to end well, but some people do, and these are the ones who slip through the cracks and become the 40-year-old creeps following your wife to the car or trying to solicit your kids on Roblox.
I suspect sexbots (and porn) are particularly exploitative of the autistic. They're an easy trap to fall into when you have to work 3x as hard to connect with people. You get the benefits of sexual release without any of the effort. There's no incentive to go the hard route and learn to work around your issues when you can just engage with a bot you can rape to death once offended. You don't learn any skills that transfer to useful human interactions this way.
