Humane launched the AI Pin in November 2023 with $230M+ in funding and pitches from ex-Apple founders. Reviewers panned battery life, latency, and a laser projector that wilted in sunlight. Sales never materialized, returns outpaced new orders, and in February 2025 HP acquired Humane's IP and team for roughly $116M while bricking existing Pins by month's end. The hardware is now a paperweight; the cloud services that powered it were shut off.
Olive was a healthcare RPA-and-AI company that hit a $4B valuation in 2021 after raising over $900M from General Catalyst, Tiger Global, and Vista. Customer hospitals reported the bots underdelivered and were difficult to maintain. After multiple layoff rounds in 2022 and 2023, Olive sold its two remaining business units to Waystar and Humata Health in October 2023 and shut down. The brand is gone; the website now serves a single sunset notice.
Babylon Health was a UK telehealth and AI symptom-checker company that went public via SPAC in 2021 at a $4.2B valuation. Its 'AI doctor' chatbot drew regulatory scrutiny from the UK MHRA over accuracy claims. After delisting from the NYSE and an attempted private rescue in 2023, the US subsidiary filed Chapter 7 bankruptcy in August 2023 and the UK operation went into administration. The brand and apps are gone.
Disco Diffusion was a free Google Colab notebook by Somnai that combined CLIP-guided diffusion with a community-tuned UI, going viral in early 2022 and seeding the prompt-engineering culture later cemented by Midjourney and Stable Diffusion. Active development on the official notebook effectively stopped in late 2022 once Stable Diffusion released and consumed the open-source diffusion community. The notebook still loads but is years out of date and runs poorly on modern Colab runtimes.
