At the risk of sounding* pretentious, the ping-ponging across the recursive footnotes is an intended and crucial part of the book. The whole "shattered narrative" was deliberately modeled on the experience of going through the expansion of television media and the balkanization of individual attention in western culture in the 90's.

Of course, that never slowed down, and we have bloody TikTok now, so it's not like it's a novel experience anymore. Read it how you like :)

*who am I kidding, I'm low-key doing an I Read Infinite Jest move. Judge away.
