We train AI, but we don't give it our playbook. Every interaction starts from scratch, imposing a silent tax on productivity and quality. Nathaniel Whittemore calls this the context repetition tax - the twenty minutes wasted each session explaining who you are and what you need. His solution on The AI Daily Brief is a personal context portfolio: a structured set of ten Markdown files - covering identity, communication style, and a decision log - that serve as API documentation for your professional self. The goal is to move beyond generic model defaults to personalized, high-fidelity outputs.
Jack Dorsey applies the same logic at the organizational level. In a conversation with Brian Halligan, he argued that every company is already generating the artifacts needed to become a self-aware entity. Every Slack message, email, and code commit is training data for a proprietary intelligence, a 'mini-AGI.' Block is actively restructuring to treat AI not as a peripheral tool but as the central nervous system, aiming to strip away the human-scale communication barriers of a 2,000-year-old hierarchical model.
Nathaniel Whittemore, The AI Daily Brief:
- The context repetition tax doesn't just waste time, it also degrades quality.
- It is a single source of machine-readable truth about who you are that any agentic system can read.
This drive for structured, owned data comes as the legal landscape shifts to hold software design accountable for harm. On Hard Fork, Casey Newton detailed how juries in Los Angeles and New Mexico are bypassing Section 230 by treating engagement features - like infinite scroll and push notifications - as defective products. These rulings, totaling hundreds of millions in damages, signal a path for future liability claims against 'sticky' AI systems, which Kevin Roose identified as the likely next frontier for product liability debates.
The push for context is a response to a deeper enterprise problem: most data was never structured for AI consumption. Whittemore's framework and Dorsey's vision both treat data readiness as a prerequisite for meaningful agentic work. They point toward a future where persistent, personal, and corporate context portfolios become the standard, owned by the user or company, not locked inside a platform.
Jack Dorsey, Long Strange Trip: CEO to CEO:
- Every single thing that we do creates some sort of artifact, whether it be a Slack message, an email, or a pull request for code.
- All these things have these artifacts of information about how the company is building, how it is failing, and how it is making mistakes.
