This short story is set in a near future where vat-grown "humans" have been created for organ harvesting, but predictably, some people have found... other uses for "growgirls."
They aren't sentient, they are basically just human-shaped meat puppets with nervous systems, but you can program them to do very simple repetitive motions (ahem), and the protagonist is a young voice actress whose sexy voice proved perfect for growgirl dialog scripts. She was supposed to remain anonymous, of course, but with a growing community of growgirl "fans," someone doxxes her.
Sex dolls have been around for a while, but the technology - both robotic and AI - is getting better and better, and I've seen a number of articles lately predicting that soon there will be a growing population of men willing to settle for an animated puppet that's almost as good as - or, according to some perspectives, better than - the "real thing." I've also seen some real discomfort, mostly from women, about the idea. Not that they actually want any of these hapless losers who'd settle for animatronic handjobs and canned "Me love you long time" dialog. But that incels will have available to them an outlet for their frustration and anger and desire that they can indulge and stew in in the privacy of their own basements. Some of this seems like understandable concern that it will warp their already warped view of women, but my own perspective is that while I can only feel pity for anyone that sad and sexless, leave 'em be.
Lauren Beukes seems to be writing more from the angry feminist end of the spectrum that regards incels as an existential threat and considers their ability to bang women-shaped fleshlights an affront to womankind. So the threads of this story are interspersed with the (predictably disgusting) online chatter of incels, and then their unleashed wrath and venom when the main character's identity as the voice of their growgirl sex toys is revealed. And there are some kind of pointless scenes with a smug Jordan Peterson character who seems to be inserted into the story just so the author can show how much she doesn't like Jordan Peterson.
It was a plausible story tying contemporary issues into very slightly futuristic technological developments, making it perfect for a SF short from Audible originals. But it did seem a bit ranty to me.
