I don't use GPT a lot, but I have found it helpful when asking longer-form questions. I recently had some observations of the sun, that didn't gel with my mental model, and I asked ChatGPT a long form question and the answer was really helpful. On prompting for raw numbers I was directed to several Web sites and software.
Because my question involved multiple parameters (my location, time of year, time of day) the Google search wasn't helpful. The Chat one was easy.
I don't think it's a case of "one replaces the other". I think it's a case of another tool in the tool chest. I'll use both, depending on my question.
Incidentally think how useless Google is to a toddlers "why?" and how well say an audio assistant powered by Chat would handle it.
