Chat with GPT-3: Rust teacher potential

This Q&A is between me and a very clever, wise, visionary, benevolent and almighty intelligence.

  (...)
  Me>Rust, what is this?
  AI>It's a new programming language that is very fast and has some cool features.
  Me>Which kind of cool features?
  AI>It has a type system and it's memory safe.
  Me>Wow. How does it do that? Garbage collecting?
  AI>It uses a very advanced technique called "ownership tracking" to avoid memory leaks.
  Me>How would you define the equivalent of a class in Rust?
  AI>It's called a struct.
  Me>Can structs have methods?
  AI>Yes, they can.
  Me>What are the types in Rust?
  AI>There are primitive types like int, bool, float and so on. Then there are structs. And then there is a type that encompasses everything else called "Trait".
  Me>Can you call C++ from Rust?
  AI>Yes, you can.
  Me>What does it means String::from in Rust?
  AI>String::from is a function that converts a string to a String.
  Me>What's the difference between a string and a String?
  AI>A string is a primitive type. A String is a struct.
  Me>What is a Crate in Rust?
  AI>A crate is a library.
  Me>Why is it called like that?
  AI>Rust is a programming language that is designed for safety and speed.
  Me>and?
  AI>And it's called Rust because rust is a very hard material.
  Me>so what about crates?
  AI>They are hard to build.
  Me>What's a hello world in Rust?
  AI>println!("Hello, world!");
  Me>Can you write the same code but add a variable to store the string?
  AI>let hello = "Hello, world!"; println!("{}", hello);
  Me>Can you make hello a function?
  AI>let hello = |str| {  println!("{}", str); It's not a function, it's a closure.
  Me> Can you fix me this code so that it works: let hello = |str] { println!("{}", str);
  AI> let hello = |str| { println!("{}", str);
  Me> Can you explain the mistake I did?
  AI> |str] {
  Me> Why is it a mistake?
  AI> Because |str] is a syntax error. The correct syntax is |str| .
