Using language translators and writing tools such as Grammarly is OK. I've seen many people here encourage and recommend them to new Hivers and to Hivers whose first language is not English. Using these tools is not a problem.
The problem comes with informative posts which were generated by a ChatGPT-style AI. I've been suckered into upvoting a few of those posts, myself, and I felt cheated when I discovered where my upvotes went.
AI is supposed to be a tool, but whoever uses this tool-- as with any other tool ever made-- needs to know the proper way to use it. What is the proper way for us as Hivers to use AI? Heck if I know.
Transparency should play a major role here. Just as we need to source the images we use and content from outside Hive (even memes?), we need to know what we're dealing with without needing to be detectives.
No one is obligated to upvote any content, and that includes content "enhanced" by AI. Just as important is for us not to deceive any readers when they encounter this content.
I'll keep away from using ChatGPT-style AI as long as I can, but I know that over time I may find myself part of a group becoming smaller with each passing day.
