Leo M. Chalupa discusses the concept of “thinking machines” and the limitations of current technology. He acknowledges that machines are excellent at processing vast amounts of data and making quick decisions, similar to some aspects of human thought. However, he argues that the term “thinking machine” is a misnomer because machines lack consciousness, self-awareness, and the ability to contemplate existential questions.
Chalupa highlights ongoing research programs focused on replicating the neuronal circuits of the human brain, particularly the cerebral cortex, at institutions like UC Berkeley and MIT. While progress has been made in understanding cortical microcircuitry, he emphasizes that we still lack a comprehensive understanding of the neuronal activity underlying the human thought process.
He concludes that, in the near term, computers will continue to excel at specific tasks but constructing a machine capable of thinking like a human requires a deeper understanding of brain functionality. Chalupa dismisses concerns about the rights of thinking machines taking over society, suggesting that shutting them down remains a viable option if needed.
