Drawing on his experience with Ghostty (1M daily users in 18 months) vs. libghostty (multiple millions in 2 months), he contends that AI agents accelerate this trend by preferring to glue together high-quality, well-documented components rather than build from scratch. The building block model lowers the quality bar for derivative works, expands awareness to niche communities, reduces maintainer burden, and outsources R&D. He also notes that closed-source commercial software faces a structural disadvantage as AI agents demonstrably favor open and free alternatives. ## Full article daily.dev links to this article rather than hosting it.
