this may be true, but you could also argue that its a free tutor for learning stuff. For example I used it for explaining topics covered in exams I had to write. I learned more than any website could. Because normal websites are filled with seo text and ads. What they write over hundreds of lines, chatgpt can formulate in 20. Also a plus note is that you can ask questions on those answers. No way to do that on websites. Most of the time I searched the web for the answer, I didnt even find it. So you could say that the productity increases.
