I've worked mostly as a data scientist / analyst but regex was being user to identify various things in the SQL database (which was viewed locally via R table). I forget the exact is cases, mostly remembering how complex some of it got... Especially after certain people were using GPT to build them.

And GPT like to make up extra bits not necessary, but my coworkers didn't exactly have the knowledge to read regex, which lead to nobody really checking it. Now it just gives me anxiety, haha.
