In Walter Isaacson's book "The Innovators: The Geniuses Who Invented the Future," the author discusses the Eniac computer, highlighting that it should not be regarded as a brain. Unlike humans, the Eniac lacks the ability to reason or think independently. Instead, it functions as a powerful tool to process and present data, enabling users to make informed decisions based on that information.

This distinction emphasizes the reality that while computers can handle vast amounts of data quickly, they do not possess the cognitive capabilities of reasoning. Instead, they serve as aids to human thought and reasoning, providing critical information that supports the decision-making process.
