The em dash was in popular use long before chatgpt. It's a useful grammatical symbol and a short dash is not a good substitute. Consider whether you'd use it if it was a dedicated key on your keyboard, if so then it's worth the small inconvenience to learn how to type it.
Not just the em dash, the whole post stinks of ChatGPT, and there are two other obvious tells in the sentence I quoted.
If you know you know.
