I read a few weeks ago here on HN about one large SAAS grinding to a halt because of a greedy selector in one line of regex. Not sure how people find old stories, it's lost to me now. But it was an excellent example of why regex is dangerous and requires a lot of care to write. I wouldn't trust an AI to write my regex unless I saw that people were finding it to be consistently better than they were are writing what they need.
