Given the code that I've seen LLMs write so far I'm not too worried for now. They are very useful to write a lot of boilerplate code quick so I use them, but they also tend to write the wrong code often and so when I use them the code is well reviewed.

Of course if this is underhanded code (not to be confused with obfuscated - I won't accept obfuscated code from LLMs) I might miss things.
