What should I ask Joe Studwell?

He has a new and excellent book coming out, namely How Africa Works: Success and Failure on the World’s Last Developmental Frontier, which I consumed eagerly.  You probably know his earlier book How Asia Works.  So what should I ask him?

For additional context, here is the opening of his home page (no Wikipedia page?):

Hello. I am an author, journalist, public speaker and occasional university teacher. I am based much of the time in Cambridge. In the 2000s I restored and lived in a home in a still unspoiled area of central Italy (the photo at the top of the page is a view from the house).

So what should I ask him?
