You don't have to be an expert; you should very rarely be using regexes so complex that you can't understand them.

It might not be obvious when you hit that point, bad regexes can be subtle, just see that old cloudflare postmortem.

Even simple regexs can be problematic, e.g. Gitlab RCE bug through ExifTools

...and if you can understand them then you clearly understand regex enough not to need ChatGPT to write them
