After avoiding AI/LLLMs like the plague, I've been asking Duck.ai some fairly detailed questions, and have been, admittedly, pretty impressed with the results (after checking its references of course). For an oldster like me, it turns the search process on its head: a regular search turns up x hits, and I try to choose what appear to be the most reputable sites among them to find an answer, and then dig through text to find it; now I'm given the answer right away, and then I just have to check and make sure that it's actually correct.
