Turing's proof

Alright kiddo, let’s talk about Turing's proof. Do you know who Alan Turing is? He was a man who lived a long time ago and was really good at solving puzzles and creating new ideas that helped make computers work.

One of the things he proved is that there are certain problems or questions that cannot be answered by a computer. These problems are called "undecidable problems".

Let me give you an example. Have you played tic tac toe before? Imagine you have a big Tic Tac Toe board and you’re playing against a computer. Is it possible for the computer to always win or will you always win?

Turing proved that there is no way to create a computer program that can always win every game of tic tac toe. The same is true for many other problems. There are some questions that can never be answered by a computer, no matter how clever it is.

So, why is this important? Well, it helped us understand the limits of what computers can do, and it had a big impact on computer science and artificial intelligence. It’s a bit like learning how to play within the rules of the game.

Does that make sense, kiddo?
