The AI graveyard: a running list of projects and startups that didn’t make it

This roundup catalogs AI products, startups, and corporate initiatives that shut down, pivoted, or missed expectations, including Relay, Character.ai, OpenAI's Atlas browser and Sora, Apple's delayed Siri, Microsoft's Recall, Notion Mail, Humane AI Pin, Rabbit R1, Huxe, Yupp, and Figgs AI. It cites S&P Global Market Intelligence's figure that about 42% of AI initiatives are ultimately abandoned by their corporate parents, attributing failures to insufficient funding, technical challenges, competition, scaling difficulty, or weak demand.
