The Forever Machine

Two professors create an advanced cybernetic brain, which they call "Bossy." Bossy can "optimise your mind...and give you eternal youth into the bargain, but only if you're ready to abandon all your favourite prejudices."[1] However, when given the choice of admitting they were wrong and therefore being able to benefit from Bossy's abilities, most people would rather be right, and Bossy's ability to confer immortality is almost made ineffective by humanity's fear of "her."
