	tl;dr: The author tested Claude Opus 5.5 against GPT-6 Astra by giving both a single prompt to build a Three.js visualization of Calvino's Invisible Cities over six hours. Opus 5.5 finished in 1h25m using 6 parallel subagents (~$74 in tokens) and produced a dramatically more polished, "mesmerizing" result, suggesting a significant leap in AI-assisted interactive design. The author notes this raises existential questions about the human role in creating interactive media.
	HN Discussion: ↓AI-generated projects feel soulless and fail to evoke engagement despite technical impressiveness ↓The visualization fails to capture the book's deeper themes of semiotics and meaning ↓The output has concrete quality flaws like inaccurate details and poor UX curation ~Conflicted acknowledgment that AI capability raises genuine questions about creative hobby work •Readers should preserve their imagination by avoiding visualizations of the book
