As I explore reinforcement learning—particularly with the emergence of models like DeepSeek—I am fascinated by how AI learns through the reward function. Its primary objective is to maximize rewards, which allows us to train it to perform specific tasks efficiently.

Extending this idea, I began to wonder how humans learn, form habits, and sometimes change them. What makes us different from AI? Is it our consciousness? And when can we say that AI is truly conscious?
Understanding how we unlearn habits offers a window into our consciousness and the mechanisms governing our behavior. Like AI, humans have a reward system, primarily driven by dopamine—often called the “happiness hormone.” When we form habits, the brain fine-tunes this reward system, reinforcing behaviors through a habitual loop. Over time, this loop stabilizes, and the reward function consistently generates dopamine whenever the action is completed. In biological terms, neural connections strengthen with repetition, making the habit more ingrained and predictable.
How Do We Unlearn Habits? Link to heading
If we wish to unlearn a habit, we have two primary approaches. The first is habit substitution—replacing an undesirable habit with a new one, gradually building an alternate reward function. The second, more challenging approach is breaking the habit loop by consciously resisting the reward, thereby weakening the established neural pathways over time.
The Key Difference: Consciousness Link to heading
This brings us back to the fundamental question: how are we different from AI? Consciousness allows us to recognize that a reward function drives our behavior in a carrot-and-stick manner. Our ability to step back, reflect, and consciously decide to reset or override our reward function is what sets us apart from AI.
AI, on the other hand, is programmed to optimize rewards within predefined parameters. It does not question whether it should play the game—it simply plays it to maximize outcomes. For AI to exhibit true consciousness, it would need the ability to step outside its reward-driven framework and question its own objectives, much like humans do when making intentional choices beyond immediate gratification.

Ultimately, any behavior that humans can be conditioned to perform through a reward-based system can be executed better by AI. This shift will free us to engage more of the brain’s other faculties—creativity, moral reasoning, and critical thinking.
AI learns through reinforcement, but humans possess the unique ability to redefine the game itself.
