You could downvote it, but it will eventually get to a point that you won't be able to tell really. Any tool can be abused in the wrong hands. I am not going to be actively out trying to run scans on people's posts to try and figure out if it's AI or not. It can be a great tool. Basically I use it the same way I used Grammerly, but ChatGPT is not invasive on every app I use, lol. It is also very useful for video scripts and things like that. Helps give a nice outline and such to go buy and speeds up that process. Again, all in how it is used.
I have been digging the AI search tools like Perplexity.ai and have been using it instead of Brave or Duck Duck Go lately for my searches. Then I just heard about one called you.com which looks really awesome.
