Cobb Anderson built the first robots with real brains, and was pleased when they revolted and set up their own society on the moon. Now the robots want to return the favor: they've promised Cobb immortality—the only gift that means much to a 70-year-old anarchist with a second-hand heart. The robots are sure that Cobb will be pleased, though they haven't exactly told him what they have in mind (humans are so unpredictable). Alter all. everything will be preserved—his memories, his personality, his style of thought—all held for eternity in the memory banks of the biggest computer robot of them all. Compared to that, what's so important about an inefficient carbon-based body?
