It would probably erode trust between people interacting online. Many of us are here to discuss issues with real people, not AI agents. When real people start to mimic the conversation parlance and cadence of AI agents it becomes much more difficult to trust that you are interacting with a real person
Personally I'm not interested in chatting with AI agents
I'm not even really interested in chatting with real people filtered through AI agents. If you can be bothered to type out a prompt to your AI you can take the time to write your own thoughts
I don't even want to read things edited (sanitized, really) by AI either
The same way I don't want my living space to resemble a too-clean laboratory, I don't want my conversation space to resemble an HR meeting. I want to interact with the messy side of people too. Maybe not "unfiltered", but AI speak is much too filtered and too polished
I chose every word in this post myself with no help from AI, then typed it with my thumbs, just like god intended
