Isn't that the whole point of Google providing it's own interpretation (sometimes several of them) of an answer to the search query ahead of the classic search results: give users what they are likely to be looking for without requiring another click?
> zero-click search problem
As a user, I see zero-click searches as a benefit, not a problem. It's a problem for people trying to use Google as a “clickstream” to waste my time and try to get a crack at my money, but then, that's exactly why it is a benefit to me.
