The Tetris effect demonstrates how sustained focus reshapes our thoughts — a principle now exploited by algorithmic platforms. YouTube, Spotify, LinkedIn, and Reddit increasingly hijack attention through recommendation engines that prioritize engagement over user intent, feeding doomscrolling, AI-generated content, and covert advertising. This "attention hijacking" effectively hands control of our mental environment to corporate algorithms.

The pre-algorithmic internet required deliberate navigation: users curated bookmarks for specific interests — gaming news, tutorials, niche blogs, wikis — and encountered harmful content only by active choice. That intentional web still exists beneath the commercial layer, accessible via RSS feeds, independent blogs, and self-directed learning.

Reclaiming attention means accepting a slower, finite internet where content isn't infinite or updated per click. Like any habit, the shift requires persistence. When we consistently choose what to consume, our cognition adapts — proving attention remains the only resource we truly own.
