I, Robot is a collection of short stories. The only relationship I notice is having a robot that seems like a human… like the genius political character in I, Robot. but now only one robot left?If I remember correctly, it spans MUCH longer than that.
The I Robot stories are set in the late 20th to early 22nd centuries, I think.
By the time the Empire books start, Earth is almost completely forgotten about, so that has to be multiple millennia, I would think. (Or was this the beginning of the Foundation books?)
Then the development of Psycho History takes about 1000 years, I think…
doesn’t feel nearly the same as foundation.
