Personal AGI: Why your skill files are your new career moat
This engineering brief covers Personal AGI: Why your skill files are your new career moat, with practical context for AI and developer-tool decisions.
The Brief
Garry Tan argues that the real AGI is not a god in a data center but a personal agent running on your infrastructure, with your memory. The differentiator is context, not model quality.
Decision relevance
Read this for workflow impact, implementation trade-offs, and the claims that need technical scrutiny before they reach team planning.
Summary
Garry Tan argues that AGI is not a singular event but a diffused personal agent you build. He contrasts rented corporate AI with owned personal AGI that compounds daily. The real leverage is in your unique context, not model weights.
He provides evidence: his own 400x coding output (deflated to 8x at floor) and YC portfolio companies with 95% AI-generated code becoming fastest growing batches. The implication: the multiplier applies to all knowledge work, and fast-growing founders treat AI as a workforce, not autocomplete.
The practical architecture: frontier model (rented commodity) + your context (owned) + a harness (open source). Skill files are markdown instructions that a smart intern could follow. The tradeoff: uncurated memory becomes a garbage dump; curation and hygiene are critical.
The political dimension: skill files are extracted cognition. The key variable is who controls them. Tan argues skill files should be owned by the individual, not the company. This changes the nature of employment and career compounding. Open source release is meant to democratize leverage.
Why It Matters
The key competitive advantage shifts from model access to owning your personal context and skill files.
