It is not really surprising. The dead internet theory is coming into being but, as you mentioned, it isnt catastrophic. AI is generating a lot of what people want, including a replacement for search.
Chatbots will end up increasing the ratio as more use them for greater purposes.
I don't think it's completely dead. For example, when I use AI, I'm the one directing it with my thoughts and ideas to make them more readable. Of course, not all creators do it this way.
The dead internet theory is the idea that more of the activity on the internet will be initiated by computers, and less from humans. We passed the 50% mark a couple of years ago.
Over time, that will get less.
Yup definitely. I used AI for the image too, which saves a lot of time haha
