I've always used —, but my writing skills were bad. I've always had a good enough vocabulary, but failed to be concise and precise. That I've learned with ChatGPT. ChatGPT writes well, except when it's hallucinating, which is very often. Or faking to be precise when you know it isn't. I believe people have been copying the style of ChatGPT, not using ChatGPT to write for them, as it will have the aforementioned issues.
