I don't get all this complaining, TBH. I have been blogging for over 25 years (20+ on the same site), been using em dashes ever since I switched to a Mac (and because the Markdown parser I use converts double dashes to it, which I quite like when I'm banging out text in vim), and have made it a point of running long-form posts through an LLM asking it to critique my text for readability because I have a tendency for very long sentences/passages.
AI is a tool to help you _finish_ stuff, like a wood sander. It's not something you should use as a hacksaw, or as a hammer. As long as you are writing with your own voice, it's just better autocorrect.
