Are applications like batteries, semiconductors, solar panels, etc. bottlenecked by the number of available materials? Also, I wonder if the discovered materials are kind of "interpolating" between materials that are already known, or if they expand the convex hull in some way. (Though perhaps it's difficult to precisely define what the convex hull of materials is.)
