In most cases, you're better off consulting an AI model for coding questions. It's been trained on millions of lines of real code, more than everyone on Stack Overflow.

Tell the agent what issue you're having and use one that integrates with your IDE so it can see your files.

So... Yes.

It depends. For really niche questions I still find StackOverflow and similar platforms miles ahead of AI. For generic / beginner questions AI surely works and unfortunately it seems like people think it’s a good idea to just post a question they find online into a LLM and copy the answer straight back to the platform to gain internet points (without even understanding the solution or validating if it actually works).
