I have mixed feelings about this.
Sure it has replaced Google for a lot of people. But was that driven more by Google breaking search and actively ranking down good results and putting blocks in the way of seeing even the bad results?
Google had (have?) people using their service out of habit but built a hostile enough environment. We have this "contradiction" where non-tech folks are supposed to be difficult to move off "what they know" yet here we are where they are using ChatGPT to search and be a doctor.
