Good god don't ask this.

Broadly speaking, there are no "talking points" we could possibly give you without further context to prevent you from looking like a brainlet. Put another way, asking a good question that indicates you are knowledgeable about the topic of the seminar requires you to understand the specific subtopics that were discussed. We could give you some random, legitimate questions to ask, but if they were essentially orthogonal to the context of the seminar itself, it would just seem like you were pulling shit out of your ass and using buzzwords that you personally don't understand.
Which would be essentially true, hence another reason not to do this. Just be honest and either ask a legitimate question that forms during your time there, or if none arises, don't ask anything. The age-old adage holds well here.
