What is a primary advantage of using an AI coding tool like Cursor for routine code edits?
It reduces the mental effort required to make common edits and lookups
It eliminates the need to understand programming fundamentals
It automatically writes entire applications without user input
It guarantees bug-free code on the first try
A developer wants to use an AI coding tool for a project involving a brand-new API released yesterday. What should they consider?
The AI will refuse to work with new APIs
The AI cannot guarantee knowledge of APIs released after its training cutoff without retrieval
The AI will automatically know about the new API since it connects to the internet
The AI will ask the developer to write the API documentation first
Why is it risky to rely on an AI coding tool without understanding the underlying programming language yourself?
The tool will delete your code files
You cannot verify whether the tool's suggestions are correct or harmful
The tool requires you to memorize all its prompts
The tool will stop working if you don't pay monthly fees
Before trusting an AI coding tool on novel work, what does the lesson recommend?
