Briefly explain Turing completeness and one common misconception about it.

# Turing Completeness **What it means:** A system is Turing complete if it can simulate any Turing machine, meaning it can compute anything that's computable given enough time and memory. Practically, this requires the ability to: - Store and manipulate data - Perform conditional logic - Loop or recurse indefinitely **Common misconception:** Many people think Turing completeness means a programming language is "powerful" or "better." In reality, nearly all practical programming languages are Turing complete—including esoteric ones like Brainfuck or even accidental systems like PowerPoint or Magic: The Gathering. Being Turing complete says nothing about usability, performance, or suitability for real tasks. It's simply a threshold of computational capability—once you cross it, all Turing complete systems are theoretically equivalent in what they *can* compute (though wildly different in how practical they are to use).
