> ChatGPT can write better than me, it can summarize better than me,
Probably. But you still need to give some input about what to write and proof-read the output.
> it can research quicker than I can
I don't think so. AFAIK, it doesn't research at all right now. When google and bing add such models to their search engines, I doubt they will be able to research quicker than a human mind. Most research queries are not responded by plain text: Search for a hotel price in a specific room for a specific date, for instance, or check the weather in a specific place at a specific time. Language models will help you to ingest and query large volumes of text, but that's something we don't do that often.
All in all, Chat-GPT is a tool to work with text. It certainly can be useful in that context, but I don't see any world-changing properties.
