"The Jesus Incident" by Frank Herbert puts clones in place of humans, with the 60s undertones of racism between clones and humans, only to turn out in the end that the people who thought they were humans were actually clones. I think Black Mirror already did that twist in the first season with robots, but it adds another level to your plot.
In the eyes of marketers, we're already the infinite fuckbots. Madison Avenue is getting nervous that as consumer fuckbots, we're spending too much time distracted with their other schemes. They are running out of ways to control (and hence, justify their ad pitches for) individual markets as we have infinite conspiracybots, infinite dumbassbots, etc.
Humanity is already 'bots all the way down. Just look at what happened to the hempbot markets.
