Post–Turing machine

Okay, let's pretend you have a very special toy. This toy is called a Turing machine. It's like a really futuristic calculator that can do all sorts of math problems really quickly. But sometimes the Turing machine gets stuck or confused and needs help to keep going.

So some really smart grown-ups came up with something called a post-Turing machine. This machine is like a special helper that works with the Turing machine to keep it going and figure out even more complicated math problems. It's kind of like a big brother or sister who helps you with your homework.

The post-Turing machine can do all sorts of things to help the Turing machine. For example, it can tell the Turing machine what to do next, or it can give it extra information to solve a problem. The post-Turing machine can even help the Turing machine learn how to do new things better!

So when the Turing machine needs a little help, the post-Turing machine is there to save the day! Together, they can do all sorts of neat things and solve really tricky math problems.
