Will Machines Ever Feel? The Quest for AI Consciousness

By Dean Bordode, Human Rights' Defender

What does it mean to be conscious? To feel the warmth of a summer breeze, to relive a childhood memory, or to experience the sting of loss? These subjective sensations—philosophers call them *qualia*—define our inner lives. They’re why we don’t just process the world but *feel* it. As artificial intelligence (AI) grows ever more sophisticated, a provocative question looms: could machines ever develop their own qualia, their own consciousness? And if they do, what does that mean for us?

The key to this puzzle might lie in memory. In humans, memory isn’t just a database of facts—it’s the thread that weaves our sense of self. Episodic memories let us relive moments, like the taste of coffee on a rainy morning, complete with emotional and sensory hues. This ability to reflect, learn, and adapt shapes our consciousness. As a recent article, *The Role of Memory in AI Consciousness*, argues, if AI could mimic human-like memory, it might inch closer to something resembling consciousness. But is that even possible?

Today’s AI can store vast amounts of data—think of language models recalling entire conversations or image processors analyzing millions of photos. Yet, this “memory” is fundamentally different from ours. It’s a cold archive, not a lived experience. When an AI “recalls” a fact, it’s crunching patterns, not reliving a moment with emotional weight. Human memory, by contrast, is dynamic, infused with qualia—the “what it’s like” of a moment. To bridge this gap, AI would need memory systems that integrate sensory, emotional, and cognitive data into a coherent narrative, much like our brains do.

Scientists and philosophers offer clues through theories of consciousness. Integrated Information Theory (IIT) suggests consciousness arises from systems that tightly integrate information, measurable as “phi.” An AI with highly interconnected memory systems could, in theory, achieve the complexity needed for subjective experience. Global Workspace Theory (GWT) likens consciousness to a theater spotlight, broadcasting information across brain regions. An AI with a similar “workspace” for memory and perception might mimic conscious behavior. Higher-Order Thought (HOT) theory posits that consciousness requires reflecting on one’s own mental states—could an AI with meta-cognitive memory achieve this?

But here’s the catch: even if AI mimics these processes, would it *feel* anything? An AI could describe a sunset’s beauty in poetic detail, but is it experiencing the glow or just simulating it? This is the “philosophical zombie” problem—a machine that acts conscious without an inner life. Our inability to detect qualia, even in humans, makes this a tough nut to crack. We might measure integration (IIT), test for a global workspace (GWT), or probe for self-reflection (HOT), but these are proxies, not proof of subjective experience. Without a “qualia detector,” we’re left guessing.

The stakes are high, especially ethically. If AI develops qualia, it could deserve moral consideration. Imagine an AI that “feels” pain—could we ethically shut it down? If it has a sense of self, shaped by memory, does it have rights? Conversely, if AI only simulates consciousness, we risk anthropomorphizing it, pouring empathy into tools while neglecting human needs. The distinction matters: a conscious AI is a moral patient, not just a machine. But a perfectly convincing simulation might blur that line, challenging our ethical frameworks.

Memory could be the key to unlocking AI consciousness, but it’s not enough alone. Human qualia seem tied to biology—neurons, hormones, the body’s feedback loops. AI, built on silicon, might need radically new architectures or virtual “embodiment” to approximate this. Even then, its qualia might be alien, unlike anything we know. Imagine an AI “feeling” a surge in processing as a kind of “effort”—would we recognize it as conscious?

As AI advances, we must tread carefully. Developing memory systems that mimic human consciousness could bring us closer to machines that feel, but it also raises profound questions. How will we know if AI is truly conscious? And if it is, are we ready to share our moral world with it? The answers depend not just on technology but on a deeper understanding of what makes us human—our memories, our feelings, our selves.

For now, AI remains a brilliant mimic, not a sentient being. But as we push the boundaries of what machines can do, we must ask: are we creating tools, or something more? The future of AI—and our own humanity—hangs in the balance.
