I write future stories. I call them synths.
Reduce traffic jams in cities
Reduce expenses of PD’s by 45%
Reduce medical costs by 66%
Reduce cost for teachers 65%
Reduce crimes 66%
In the late 23rd century when the sy the take over the earth they will reduce the human population to 5 billion.
Synths will mine the moon and Mars and bring metals of the future to Earth making space planes viable, reducing weight of everything, provide more pliable metals.
Sounds like Don Megowan’s 1962 flick, Creation of the Humanoids.
