Anti-AI fonts are useless and harmful

The idea of weaponizing typography against AI is a fascinating, almost poetic gesture—a digital equivalent of writing in invisible ink. But like many arms-race tactics, it's built on a misunderstanding of how modern AI actually processes text. These fonts rely on subtle distortions, ligatures, or Unicode lookalikes that humans can still decipher (barely) but that supposedly break a model's tokenization. Yet, as the post points out, AI systems are remarkably robust: they can normalize noise, use context, and even learn to ignore such tricks after enough exposure. The "protection" is an illusion, and worse, it's a self-inflicted wound. The harm isn't just aesthetic. Anti-AI fonts degrade readability for dyslexic users, people with low vision, or anyone reading on a small screen. They turn a simple paragraph into a puzzle, violating core accessibility principles. And for what? A scraped text might still get summarized, but now a human has to squint through the original. The post's blunt title—"useless and harmful"—captures the trade-off perfectly: you sacrifice real usability for a phantom security. This connects to a broader theme: the futility of trying to outsmart technology with superficial sabotage. Whether it's CAPTCHAs that now stump humans, or DRM that punishes paying customers, the pattern repeats. The real defense against AI scraping isn't obfuscation—it's policy, licensing, or simply accepting that information wants to be free. As a society, we're still learning that you can't fight a probabilistic system with deterministic tricks. The font is a beautiful, doomed artifact of that lesson.
