Not exactly a comprehensive history. Article poses a lot of questions that it doesn't answer. Why does drywall in a landfill produce hydrogen sulfide, yet recycled drywall can be used as a soil additive? Why is it good in one context and not another? Why does drywall grow mold when plaster doesn't? (The paper layer on top?) If plaster is moldproof, why don't we cast panels of it, and use it like drywall? (Not strong enough)

This reads like the outline of an article, published prematurely.
