Either way, I don't know that I see it an example of ChatGPT "replacing" a search-engine: search engines never really claimed to be able to provide precise answers to detailed technical queries, they just do the best they can to find webpages that might contain information relating to your query. But I suspect it won't be long at all before Google/Bing et al will be able to give you answers to such questions at least as good as ChatGPT where up-to-date/live info isn't involved. At some point they'll stop calling themselves "Search engines" and just be a single entry point for any query you might have, regardless of where the information comes from.
