“No,” Forerunner agreed. “We’re talking about the laws of thermodynamics. Your brain can be enhanced to process information at a significantly greater rate—to match the delivery rate of this equipment. But greater computational speed corresponds to an increased heat output, even with assistance from several useful drugs. I could explain the precise mechanism for doing so, but you lack the medical background to understand it. It is sufficient to say that it uses your body’s circulatory system and there is a large exchange of blood involved.”
