Who uses ChatGPT more than Google?

I pretty much use Google now only for what search engines were originally created for - finding websites.

For any kind of researchy question, ChatGPT is a beyond killer app.

Being able to ask it summarize, at some variable level of detail as you desire, basically any topic under the sun, and then being able to refine that answer to change the focus, level of detail or even formatting is unbelievably powerful.
