I just. Think. If you want to write about silica just say that!! Calling it sand is sloppy!!
Also has lines like "Sand is what will help us pull millions out of destitution and poverty" re: concrete and that "us" vs "millions" makes some interesting assumptions!! Also he's talking about concrete which, my guy
To be fair this book is basically "an economist just found out commodities are real things from places" my expectations should be lower
