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 Character.ai's bankruptcy filing, Ollie's shutdown, OpenAI's discontinued Atlas browser and Sora, and hardware failures like the Humane AI Pin. It cites S&P Global Market Intelligence's estimate 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 user demand.
