GPT-4 doesn't work for legacy systems in dying languages. It only "works" for things that are well-documented on the internet, or described in what books were included in the dataset.
I can't think of a situation where you'd go from spending hours on Google to being unblocked in seconds. If you're spending hours on Google, then your first dozen search queries aren't turning up the information – in which case, GPT-4 wouldn't turn up the information immediately, either! (It would say something, but it's unlikely to be based on a true story.)
