Microsoft and IBM build OS/2 together — then split over Windows
[RECORD.TXT] · cat --full
In 1985 Microsoft and IBM agreed to jointly develop OS/2, an advanced operating system intended to succeed MS-DOS. But as Microsoft's own Windows gained momentum — especially after the hit Windows 3.0 in 1990 — the partners' priorities diverged, and the alliance unraveled around 1990-1991. Microsoft bet everything on Windows while IBM carried OS/2 largely alone; Windows went on to dominate the PC, and OS/2 faded. The 'divorce' cemented Microsoft's independent control of the operating-system business.

Gates warns AI could be used to design a bioterrorism weapon
In his January 2026 'Year Ahead' annual letter and subsequent remarks, Bill Gates warned that an even greater risk than a natural pandemic is that 'a non-government group will use open source AI tools to design a bioterrorism weapon.' Gates identified two AI dangers he said society must manage — misuse by bad actors and disruption to jobs — and drew a comparison to COVID-19, invoking his 2015 TED talk about pandemic unpreparedness. He argued the technology must be deliberately developed, governed, and deployed, and urged governments to use 2026 to prepare before AI's risks become unmanageable.

Gates backs a $1 million prize for AI-powered Alzheimer's research
Bill Gates joined other funders backing a competition to harness artificial intelligence for Alzheimer's research, with the Alzheimer's Disease Data Initiative offering a $1 million first prize for 'agentic AI' that can accelerate discovery. The effort reflects Gates's growing personal focus on the brain — shaped by his father's experience with Alzheimer's — and his belief that AI and big data can speed progress in a field long marked by setbacks. Application rounds ran from 2025 into 2026.
