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

Apple's Siri faced significant delays and a $250 million settlement over marketing claims, while Microsoft's Recall faced privacy concerns and was delayed. Other notable failures include Notion Mail, Humane AI Pin, and Rabbit R1, which struggled with technical and market challenges. Character.ai, despite initial success, faced legal issues and eventually filed for bankruptcy, while OpenAI's attempts to integrate multiple AI features into a single app were met with user backlash. These failures highlight the complexities and risks in AI development and deployment.
