I have worked with quite a few people committing code they didn't fully understand.
I don't meant this as a drive by bazinga either, the practice of copying code or thinking you understand it when you don't is nothing new
Yes and if they copy and paste code they don’t understand then they should disclose that in the commit message too!
Pre-LLM, it was much easier for reviewers to discern that. Now, the AI-generated code can look like it was well thought out by somebody competent, when it wasn't.
