Hi! I’ve read the Foundation trilogy and heard that to understand sequels and prequels I need to read the Robot series (especially the sub-series about Lije Baley). So I’ve read „Mother Earth” and started „The Caves of Steel”. My question is: Why were robots forbidden on Earth during the events of „Mother Earth”, but were not banned during the early robots series, and why were they allowed in the Outer World? I got that they are allowed during events of „The Cages of Steel” because of the Pacific Project. But did I get it right that the Pacific Project failed? Cause objectives of the project were:

1. Temporarily isolate Earth from Outer Worlds (DONE)
2. Force earthmen to control birth, use robots, and hydroponic farms. (DONE)
3. Till the time of new contact of earthmen and the spacers, the spacers either die out from diseases or evolve to the state where they are not racists toward earthmen (FAILED, cause spacers in the Spacetown still are as much racists as spacers in “Mother Earth”)

So there will be any explanation why the Paciffic Project failed?
