Bing Chat Assistant is better than Google, Bing search, or DDG today. If I search for "how do I do X in software Y" on a normal search, I get zillions of dead-link-filled MS pages, some interesting tangentially-related stackoverflow posts, and a bunch of old blogspam.
If I ask the robot, I often get "no, there's no supported way to do that officially" which is the clear clean answer I can't find elsewhere. Or sometimes it misunderstands the question and gives me a tangentially-related result, which is bad but is the same thing I get from Google via StackOverflow, except Bing is much more responsive to me saying "no, I didn't mean that way, I meant this" in which case I often get either the right answer or the "no" answer, which is still good and accurate! The problem is as you iterate, the conversation accumulates cruft and becomes more erratic and hallucinatory.
But right now, with the level of SEO that has ruined all major search engines (ironically partially caused by AI), Bing Chat is the best search on the market now imho. <homer>The cause of and solution to all of life's problems </homer>
So yeah, in terms of "things where AI has lived up to its potential"? It is winning the search war today. Everything else is something on the horizon in various distances (art, music, text generation, true general AI) but better search for information is here right now.
