A thought from OpenAI Build Week in London about uncertainty, pricing, and building where no reliable pattern exists yet.
Could One Word At A Time Make Reading Easier?
A practical experiment with Focus Reader, dyslexia, attention, and comprehension.

AI can advise, challenge, and inform. It cannot take responsibility for the judgement you choose to make.
You Cannot Vibe What You Do Not Know
AI can help us build at extraordinary speed. It cannot reliably warn us about rules, risks, and details we do not yet know exist.
Your AI Is Not An Employee Yet
Calling an AI tool an employee does not make it ready for work. A practical safety guide to onboarding agents through bounded tasks, context, supervision, tests, least privilege, and earned authority.
Making Agentic Work Visible
Why Tony is replacing message streams and human issue lists with bounded work packets that agents can triage, discuss, approve, execute, and receipt.
