ChatGPT is a better Google. Instead of finding a page that matches your query, it can interpret the results of multiple pages and output a response that's more tailored to your exact prompt. The only downside to this is that ChatGPT becomes your primary source instead of the page(s) it sources content from, so you can't verify it's authenticity.

But the "extremely positive applications" to ChatGPT are, at the very least, the same positive applications of any other search engine.
