Writing in the Age of AI: Why ‘Spiky’ Style Still Wins Over Smooth Optimization

Here’s a paradox worth exploring: as AI language models generate increasingly polished content, human writers are discovering that distinctive voice matters more than ever. The hedgehog vs porcupine distinction in writing reveals something crucial—porcupine writers maintain sharp, distinctive angles while hedgehog writers chase universal appeal. In an AI-saturated content landscape, the porcupine approach (maintaining those quills, those controversial takes, those unconventional perspectives) cuts through noise better than perfectly optimized prose. The question isn’t whether AI can write smoothly; it’s whether smooth writing still captures human attention.

The Takeaway

This week reinforces an emerging theme: 2026 will be defined not by choosing between human expertise and AI capability, but by understanding where each excels. Whether you’re debugging Java errors, scaling commerce infrastructure, or refining your writing voice—maintain those distinctive angles that only humans can provide.
