Fountain pens, Warhammer tabletop miniatures, and film cameras have acquired a collective label: the anti-AI portfolio. Journaling, sudoku, and puzzle books belong to the same category. Non-digital pursuits are staging a comeback.
The constraint these products share is the absence of algorithmic mediation. Film photography carries a fixed cost per frame and requires chemical development, frictions that digital cameras eliminated deliberately. Warhammer kits demand manual assembly and painting across many hours. A fountain pen requires deliberate ink management and a slower pace. The throughput is low by design.
Sudoku and puzzle books occupy the same position in the stack: bounded tasks with a natural endpoint, no recommendation engine to extend the session past completion.
The economics are behavioral. Film development carries a per-frame cost that digital photography eliminated. Puzzle books and sudoku volumes have cover prices where app equivalents typically run on advertising. Warhammer requires a time investment that mobile gaming was specifically designed to avoid. Buyers are paying in money and hours for the friction.
The framing as an anti-AI portfolio is the specific signal. Analog revivals have run on nostalgia before, but positioning this category explicitly against AI-mediated environments places it in the current technology moment, not a generic retro preference. Journaling sits at one end: pen to paper, no cloud sync, no feed, no algorithm reading the draft back to the writer. The cost is paper.
