DeLillo's obsessive catalogs of supermarket aisles, brand names, and television schedules don't predict anything.

They document a present condition already calcified into theology — a system where Jack Gladney walks into the Murray Jay Siskind-curated supermarket not as a future space, but as the deepest operating system of American consciousness, already installed and already generating the feeling that safety lives in abundance.

The novel's actual mechanism shows that choice itself becomes a narcotic. The act of moving through rows of identical products arranged by category creates the illusion of control through visibility — and Jack doesn't fear death less because he buys more cereal, but because the supermarket's architecture tells him that everything from pain relief to breakfast has been sorted, named, and made available. The fear doesn't disappear. It gets relocated into the shelves.

When the Airborne Toxic Event arrives — the moment when the invisible, the unnameable, the unsorted finally enters American life — Jack's entire framework collapses. But not because he discovers that shopping won't save him; rather because he discovers something worse: that he'd already known this all along. The event doesn't reveal consumer culture as false. It reveals that Jack inhabited consumer culture precisely because he knew the truth already and needed the supermarket to help him forget it.

What DeLillo caught was that Americans didn't develop this religion slowly — it was already the dominant spirituality of the home, and we needed only to describe what we were already praying to.
