Your suggestion is similar to that of someone saying that plagiarism should be condoned based on its usefulness. People who plagiarize, those who use text spinning bots and those that use AI to generate texts are lazy and are not interested in organic discussion here.
Plagiarism is stealing others' work. It is unethical at the least. Some people think that generative AI is a rephrasing bot. It is not. I get what you're saying (and others in this thread) - there should be ways to prevent generated spam (which now is extremely easy to produce) from people whose only goal is financial gain. But, fighting AI is not the right approach. Not everyone who uses AI is lazy and doesn't add to the organic discussion. But my main point is that those anti-measures won't work. This is a losing battle. A more effective approach would be combating babble, AI or not AI.
Used by everyone to generate texts so that they can communicate to their colleagues, who are also using AI to generate responses? Come on... you know how silly it sounds

Write a response to this statement "AI used by everyone to generate texts so that they can communicate to their colleagues, who are also using AI to generate responses? Come on... you know how silly it sounds", incorporate that saying that something is silly doesn't make it silly and doesn't help the argument and that many professionals already use AI tools to communicate efficiently. Make the response concise.
Labeling something as "silly" in an attempt to dismiss or undermine its credibility doesn't actually add any substance to the argument. Many professionals and organizations use AI tools to generate texts and responses, which can save time and improve communication efficiency. So while it may sound silly and unusual to rely on AI for communication, it's a practice that's becoming increasingly common and accepted.
By the way, the company I for integrating AI tools to streamline communication.
