Don't be stupid. This is no where near the same thing.
However, not everything is considered plagiarism just because I read it somewhere and reproduced it somewhere else. If someone described something in detail on a forum and ChatGPT took that information from across the internet and reproduced it for me. That's not necessarily plagiarism.
My point being, there is an enormous amount of information on the internet that is free from plagiarism.
