It could be that they're setting up some new category related to tech or something, that would probably be my first attempt to rationalize why they sent the request to me. However, I think that a few minutes later I would've thought "but why would they ask an engineer and not an academic who has done research into this particular technology's contributions to economics?".

But, yes, I believe that the fact that software is transforming so much stuff all the time and we developers get to work with experts from all kinds of fields if we're lucky like agriculture, medicine, geology, finance and what not can give us a false sense of actually being an authority on any of the things we write software for.
