What are sets of two people where if they had a couple video calls together, the world could greatly benefit? I mean realistically, not just in the hypothetical case where they take an unlikely liking to each other. I mean based on the ways they could benefit each other or the information that one of them has that could help the other, as well as the likelihood of that information being received by the other party in a way that influences them.

It could also be interesting to think about the ways that this question applies to people you know personally.

In an ideal world, people would suggest great possible connections, and then people reading the thread may know one or both of the people and could make the intro happen. So if you know one of the people mentioned and could make an intro if there's someone that knows the other person, please comment on that answer.
