Truly useful? Personal take, but the usefulness of these tools to me is greatly limited by their knowledge latency and limited modality. I don't need information overload on what playtime gifts to buy my kitten or some semi-random but probably not very practical "guide" on how to navigate XYZ airport. Those are not useful tips. It's drinking from an information firehose that'll lead to fatigue, not efficiency.
