What Is AI?
Two Kinds of Smart
You are previewing the first lesson — free to explore.
You are smart in ways a computer will never be. You can smell rain coming, comfort a friend, and invent a game with new rules in seconds. A computer is smart in a completely different way — it can search a million recipes in under a second, but it cannot taste any of them.
AI is when a computer performs tasks that normally need human thinking — like recognizing a face, understanding a sentence, or predicting what happens next — by finding patterns in data instead of following one fixed set of instructions.
That last part matters. A calculator follows exact rules a programmer wrote by hand: press 2+2, it always returns 4 the same way. AI is different — nobody wrote a rule for 'what a cat looks like.' Instead, the AI was shown thousands of cat pictures and learned the pattern itself.
A traffic light follows a rule: red, then green, then yellow, on a timer — that's not AI. A traffic camera system that watches real traffic and decides when to change the light to reduce jams — learning from patterns in the data — that's AI.
