There's a few languages/tools I use often but am not an expert in and have been using Claude 3.5 to help me work with existing code. On paper this is a perfect use case. In practice it's like working with an intern that has google in front of them and enough jargon to convince me what they're saying isn't bullshit. Eventually, I'll be able to coax the answers I need out of it.

I'll say though the fact AI can't say "I don't know" and closely related "that is not possible in the context you've given me" combined with the inability to reason is what gives you results that look OK but are subtly trash.
