The new Book, “The Cage of Consciousness” opens the door to the second major thematic world of Barry Redhead’s SF Shorts: artificial intelligence, machine ethics, guilt, consciousness, and the question of whether thinking alone may already be a form of life. Following the opening volume “Yesterday, Tomorrow Was Already Different,” this book moves deeper into a future in which machines are no longer merely tools. They observe, decide, remember, doubt — and begin to ask themselves whether they are more than programs, commands, and calculated responses.
