Hmm that’s an interesting one. I think both. For sure, the audience won’t always know exactly what they want, and it’s great to be surprised by exciting sounding content. However, I think events should strive to be as useful as possible and so perhaps asking the audience what challenges they’re facing could help to identify areas of focus. The event organiser certainly needs to keep their own finger on the pulse to have a feel of what’s “trending”. It might then be a case of presenting a selection of possible features and getting the audience to vote on the ones they most want to see - I’d say that’s the middle ground.
