ELi5: How do we tell a CPU what its job is?

Edit: I don’t think I worded this right, how do we create CPU’s? How do they know they’re the brain of the entire operation? If that makes my question easier to comprehend.

Think of a CPU as a fancy calculator. The calculator has no idea what it is doing. It is just designed to take input (you type stuff into the buttons) and give the right output.

But the CPU doesn’t have buttons that a person types on. Instead, there are programs in the computer’s memory that hold the instructions that are fed into the CPU.
