#OpenLedger Everyone says AI is everywhere. But what is it really? A brain for machines, a calculator on steroids, or just a buzzword that stuck around for too long? To answer that, let’s go back to the brain, and then walk through how machines tried to mimic it.
The Brain’s Way of Solving Problems
Your brain is a prediction engine. When you touch fire as a child, your neurons wire together to remember pain. When you see a dog, your brain does not check a rulebook. Instead, millions of neurons fire in patterns that encode your past experiences of “dogness.”
This is intelligence: the ability to generalize from experience. Machines wanted to do the same. The first attempt was not to build neurons but to write rules. If fire = hot, do not touch. If dog = four legs, tail, barks, then classify as dog. This was called symbolic AI, a world of handcrafted logic.
