The modern computer's central processing unit (CPU) traces its lineage to the humble calculator. Today's CPUs, with billions of transistors, can perform complex tasks that early computers, which filled entire rooms, could hardly dream of. A fascinating fact is that some CPUs now incorporate AI capabilities directly into the silicon, allowing for real-time machine learning processing. This advancement blurs the line between traditional number-crunching and advanced intelligence operations within the same chip. What's a computer fact that fascinates you? Share your own insights!
