Cybernetic Brains

It was supercivilization, a Utopia. At its core were the Cybernetic Brains, brains taken from geniuses who were promised they would live forever.
Then engineer Al Demming discovers the truth accidentally, the terrible truth transmitted to him by one of the brains. The brains are in reality slaves and in terrible torment. It was now up to Demming to stop the inhuman practice.
Just when he planned to make the announcement to the Governing Board, Demming learned that the Board knew about the hideous living death. What was the real reason behind the facade? How could he convince the Board to suspend the system before the Brains revolted and destroyed the world?
