The subject of the impact of artificial intelligence on society is more than interesting. Based on this, the writers and filmmaker have projected their dystopias from the world of tomorrow, closer and closer, what you point out about the sex dolls are already, an incipient reality that points us to Blade runner in our days.
Modern humans seem to succumb to obsolescence, after 200,000 years of fabulous innovations, before their own creations. I can't imagine the repercussions, maybe the Cylon (Battlestar Galactica) will take over. However, man has shown great adaptability throughout history, and surely, as an intelligent species, this stage of the course of history under construction will be no exception.
Superficiality and banality have always accompanied us, so the central problem does not really lie there. I think it is focused on each time the power of influence achieved to the detriment of the environment and ourselves. A paradox in itself, an intelligent being who acts irrationally to his own detriment.
