Section 1
The big idea
AI is so confident that it sometimes invents code that LOOKS right but won't run. It might call a function that doesn't exist or use a tool the wrong way.
Some examples
- AI says 'use the magicSort() function' — but no such function exists.
- Code looks perfect but throws an error the second you run it.
- AI might mix up two different programming languages.
- Always run the code to see if it actually works.
Try it!
Ask AI for a tiny program. Try to run it. If it errors, ask AI to fix it. Try again.
