AI is named after brains but works in a totally different way.

The big idea
People call AI a 'neural network' because it was inspired by brain cells. But AI doesn't really work like a brain. Your brain has feelings, memories, and a body. AI just has math.
Some examples
Your brain uses food for energy; AI uses electricity.
Your brain remembers your birthday party from 3 years ago; AI doesn't.
Your brain learns by playing; AI learns by reading text.
Your brain has 86 billion cells; the biggest AI has even more numbers, but no feelings.
Try it!
Think of one thing your brain can do that AI can't (like feeling cold). Tell a friend!
