Is intelligence just a calculation, or is there a felt quality?

In short: We can build machines that outthink us, but can we build machines that feel? Philosopher Susan Schneider argues that while AI is becoming increasingly capable, there is a fundamental distinction between processing information and having a subjective experience—the internal spark of what it actually feels like to be alive.

The core of the debate lies in the 'hard problem of consciousness.' While science is mapping the neural basis of the brain, many philosophers argue that even a perfect neuroscientific map cannot explain why information processing results in a felt quality of experience. It is the difference between a computer identifying the scent of bread and a human actually smelling it. This 'felt quality' is what defines consciousness as an internal, subjective reality rather than just a functional output. This internal perspective exists during every waking moment and even while dreaming. It represents the subjective reality of being an individual. This distinction remains a central puzzle for researchers today.

To understand the scale of the human mind, Schneider notes that the brain is the most complex organ in the known universe. With nearly 100 billion neurons—comparable to the Milky Way's stellar count—it holds a quantity of neural links exceeding every star in the cosmos. Such immense intricacy provides the seat of consciousness, enabling people to look internally and contemplate their own being. This complexity allows for the unique ability to reflect on our own minds. Humans use this internal gaze to contemplate their own intelligence. We are essentially complex beings possessing a spark of awareness.

Current AI, despite its impressive feats in games like Go or Chess, operates on fundamentally different principles than biological brains. Even 'neuromorphic' AIs, which aim to mimic brain architecture, fall short because we do not yet have enough knowledge to truly reverse-engineer the biological brain. Because today's hardware and algorithms do not compute like human biology, it remains too early to determine if science fiction will ever become science fact regarding conscious machines. Programs like AlphaGo utilized techniques that surprised their own creators. These systems do not compute in a way that resembles human thought. We currently lack the necessary data to accurately reverse engineer our own biology.
