Do you know what pattern matching is great for? Finding commonly cited patterns in long debug log messages. LLMs are great for brainstorming problem solving. They're basically word granularity search engines, so they're great for looking things up are more niche knowledge that document search engines fail on. If the thing you're trying to look up doesn't exist, it will make shit up so you need to cross reference everything, but it's still incredibly helpful. Pattern matching is also great for boilerplate. I use the codium extension and it comes up with auto complete suggestions that don't have much logic, but save a good amount of key strokes.

I didn't think the foundational tech of LLMs are going to get substantially better, but we will develop programming patterns that make them more robust and reliable.
