Just today, I think that I got a useful citation in DuckDuckGo’s Search Assist (AI stuff) sources for the very first time. The sources it lists have hitherto invariably been already right there in the regular results, or actually not supporting the AI output at all (the far more common case). There was also a useful regular search result in second or third position, but the one in the Search Assist citations was better, and not in the regular search results, even on the second page.

And I’ve tried Google’s once or twice and seen it used once or twice, and used ChatGPT exactly once, last week, and I was not at all impressed by any of them. Their output, for what I’ve personally seen, has been nonsense, obvious, or unverifiable.
