At the end of the day, you're still responsible for reading the email before you send it. I don't think it matters how the email was written. I think the final content matters more. There's many ways to prompt an AI, both carelessly and with extreme attention to detail.

For example, I typed this message. But I'm sure with careful massaging, I could get an AI to write the same thing, word-for-word. The laziness you're referring to probably happens even if the manager is typing the email out themselves.
