The footnotes also serve the purpose of structurally fracturing the narrative in a way that mimics the fractured, splintered nature of our lives realities today. Think about our daily information flow. How often are you interrupted by, say, social media, advertisements, email pings, calls, etc. Modern life is a million pieces of info and content coming at you in a kaleidoscopic blast. I think he’s exploring that by forcing readers to physically flip back and forth from footnotes to narrative and blurring the boundary between which is which. At least that’s how I think about it 🤷‍♂️
