It’s obviously quite effective or all the people who are not checking their email would not be crying all over the Internet about how they’re going to get caught by it.
Literally send any reply. Elon was even replying to tweets about people sending AI generated replies saying that would be fine.
It is less effort than your multiple replies to me explaining why people should not have to answer their work email.
It's not that replying to the email is hard. That's never been the point. The point is that you got a new boss, and his new best friend who doesn't work for the company just sent you an email that says "Tell me 5 things you did last week or you're fired, also feel free to bullshit it or make an AI reply, lol". It's stupidly unprofessional and disrespectful, and not the way the company should run.
Replying to an email is easy. Replying to an email by an outsider who is threatening to fire you is bullshit.
