I have to use a ton of regex in my new job (plz save me), and I use ChatGPT for all of it. My job would be 10x harder if it wasn't for ChatGPT. It provides extremely detailed examples and warns you of situations where the regex may not perform as expected. Seriously, try it out.
It might be because I've been using GitHub more frequently in recent months, but I have definitely noticed more disruptions than normal. Our engineering team seems to mention issues almost weekly now, when they used to be fairly rare in the past.
