The ghost in the AI machine

Despite centuries of research, scientists still lack a clear definition or test for consciousness, yet AI companies are already debating whether their systems might possess it, with Anthropic's CEO acknowledging uncertainty about his models' consciousness while the AI itself estimates a 20% probability of being conscious. This premature discussion reflects commercial incentives and human tendency to project consciousness onto sophisticated mirrors of our behavior, though the scientific case suggests consciousness likely requires biological embodiment that current AI systems fundamentally lack.
