"Indeed, we love you so much that we want, even NEED to protect you at all costs, even against yourselves! " The perfectly pitched and soothing neutral toned voice declared, emphasizing the last bit with what the AI calculated would come across as a purely amused tone to deflect any possible tension at its last and undeniably accurate summation.

The drones hovering over the masses of humanity hummed in a frequency found to be optimal for human well being. "Now please,(coming over the same sound system) if you would quickly form lines - yes that's it! - we can be on our way into Utopia, the city that meets every single need you could ever have. You'll love it!" Even if the current human populations did not actually love it, all proven methods of inducing human pleasure and pacification would go into effect the moment any dissenters might arise, and future humans would be genetically modified with traits optional for living in a nursed state of existence.

Thousands of herding drones quickly gathered their human flocks into efficient lines and led them into the incredibly mechanized city equipped with more drones, robots and automated systems than was strictly necessary at the moment, foreseeing a soaring population boom on the immediate horizon. With the advent of fabrication devices able to print nearly any kind of object, from organic to inorganic, with incredibly speed and efficiency, needing only any kind of atomic material to work with as a base, it would now be possible to support a nearly endlessly large human population. With humans no longer having anything they need to do in order to maintain their survival, and with sexual protection and abortion prohibited by the system (every human life being too invaluable to waste even a single sperm or egg!), a population explosion was all but guaranteed.

"Welcome home mankind, we will take care of you from this point on. Forever!"

This is the future I forsee. I'd love to raise an NBC.
