Garry Tan: Own Your Intelligence
Main summary
Key takeaways
Main ideas / concepts / lessons
-
Spinoza as a model of “owning your intelligence”
- Baruch Spinoza is presented as an extremely “canceled” figure: excommunicated by his Amsterdam Sephardic Jewish community at age 23, with a ban that included social/financial exclusion and no repentance clause.
- He refuses offers of money to stop building and instead pursues truth and usefulness.
- He survives an attempted stabbing, keeps the scar, and turns his exile into creation—grinding lenses by day and writing a dangerous philosophical work by night.
- Key lesson: when deprived of comfort, compensation, and permission, keep building tools and knowledge.
-
Conatus: the internal engine
- Spinoza’s concept Conatus is framed as the drive in living things to persist and increase capability.
- Success isn’t attributed to resumes/titles; it comes from amplifying conatus with tools.
-
A “Spinoza update” about intelligence (AGI is not an event)
- Traditional view: people wait for AGI like a singular threshold/event (“a god in a data center”).
- Reframed view: intelligence is diffused/infrastructure, appearing through everyday systems and agents working continuously in your context.
- Personal AGI is introduced:
- Not a rented subscription chatbot.
- Not corporate AGI you don’t own.
- Yes to an agent that runs on your infrastructure, uses your owned memory, executes your procedures, and improves with your usage.
-
Personal AGI as an owned “asset,” not consumed “product”
- Corporate AGI (described as subscription/rent):
- resets with tab closure,
- relies on corporate knowledge,
- can be “lobotomized” by the provider’s changes.
- Personal AGI (desired):
- an agent that reads from your memory,
- runs your tools,
- composes/improves daily based on your life.
- Corporate AGI (described as subscription/rent):
-
Why this is happening now: agent leverage, especially for coding
- Speaker anecdote:
- As a YC partner in 2013: shipped ~14 useful lines/day.
- In a current YC full-time role: output is argued to be ~400× (with caveats about verbosity).
- Generalized beyond coding: design, PM, growth.
- YC portfolio observation:
- Winter 25 batch shows many companies with ~95% AI-generated codebases and rapid growth.
- Core takeaway:
- Winners treat AI as a workforce, not autocomplete.
- Leverage comes less from model weights and more from context relevance and choosing the right step in the workflow.
- Speaker anecdote:
-
Working memory vs “agent memory”
- Human working memory: ~7 items (±2).
- AI agents can handle far larger contexts (tokens/pages), enabling needle-finding and synthesis across many documents at once.
- Implication: organizations/processes built for “seven-digit brains” are becoming outdated.
-
“G brain” / personal agent architecture
- Speaker describes a personal system (“G brain”):
- a knowledge wiki plus an agent that compiles/curates/searches personal history,
- avoids re-asking what it already answered,
- uses context before drafting/responding.
- Example workflow:
- Inbox triage while sleeping
- Morning briefing rather than an email pile
- Pre-meeting prep docs referencing prior decisions and changes
- Research cross-referenced against personal interests and filed automatically
- Speaker describes a personal system (“G brain”):
-
Skill files: the core unit of execution
- A skill file is described as:
- a page of clear instructions in English (Markdown),
- specific enough that a smart intern could follow it (clarity test),
- executable by an agent (not magic).
- Principle: “Fat skills, thin harness”
- Skills contain most of the task logic; the harness is lightweight glue.
- A skill file is described as:
-
Latent vs deterministic computation
- Emphasized separation:
- Latent space computation: judgment, preference, taste—steered by Markdown instructions
- Deterministic space computation: arithmetic/SQL/logistics—run via databases/scripts
- Failure mode: letting the model do deterministic work poorly.
- Fix: use a model + database/script split.
- Emphasized separation:
-
Hygiene / provenance to prevent confident wrongness
- Warning: a brain without curation becomes a garbage dump—retrieval can return stale/wrong facts with confidence.
- Mitigation:
- memory hygiene,
- provenance on facts,
- contradiction checks when new info conflicts,
- a “librarian” role that prunes.
-
How to turn leverage into organizations
- A skill file is likened to an “employee.”
- A resolver/task routing layer resembles an org chart.
- Implication: you can “incorporate” an organization of one (plus agents) before traditional company assets (co-founders, logo, deck).
- Anecdotes:
- YC summer 24: startup goes from launch to nine-figure revenue in eight months with very small headcount at high revenue levels.
- YC winter 24: high annualized revenue with relatively few people vs historical norms.
-
Political thesis: ownership determines your future
- Main caution: skill files can represent either:
- ownership (you keep them when you change jobs), or
- extraction (company keeps them under IT policy; you leave without your compounded judgment).
- Fictional support engineer example (“Maya”):
- Version 1: skills live in her repo → she moves jobs with accumulated expertise.
- Version 2: skills live in company repo → skills continue without her; her judgment is effectively removed.
- Doctrine statement:
- Own your skills; otherwise your job becomes the skill file you don’t control.
- Historical framing:
- Spinoza was offered money to stop; modern equivalents are framed as arrangements that let you “stop building comfortably.”
- Leibniz visiting Spinoza illustrates how powerful ideas can be contested and even misrepresented; the talk focuses more on adoption curves for agent-enabled workflows.
- Main caution: skill files can represent either:
-
Objections addressed
- Objection 1: models improve so harness becomes obsolete
- Response: differentiation shifts toward context and library ownership; better models amplify what your library does.
- Objection 2: isn’t this just RAG?
- Response: retrieval is a primitive; the product is what makes you “worth retrieving from,” including enrichment, linking, and contradiction arbitration.
- Objection 3: what if your life leaks?
- Response: mitigate via custody/keys—run on your own infra under your own keys rather than scattering context across corporate cloud accounts.
- Objection 1: models improve so harness becomes obsolete
-
Why open source
- Claimed because it can be done (“because I can”).
- Powerful leverage tools should be distributed to avoid creating a private priesthood.
- Building in public and adoption curves lead to copying/clone dynamics.
-
Final moral / closing vision
- Personal AGI is framed not as a benchmark/demo, but as aimed architecture for one person’s real needs (example: a father building a library/agent for a child’s rare epilepsy).
- Closing credo:
- Build what others won’t.
- Share tools.
- Create institutions/leverages so effort goes straight to work—not through decades of hiring, funding, and permission.
Methodology / “how-to” instructions (detailed bullet list)
The 5-step setup the speaker recommends (in order)
-
Step 1 (tonight): pick a harness and run an agent on your own machine
- Example harness/agent options mentioned:
- OpenCloak (as named in subtitles)
- Hermes agent with “G brain”
- Hosted/open alternatives (example: gbrain.io as a hosted option)
- Claims Codex / Cloud Code-type options can work for “99%” of the approach
- Principle: concepts matter more than any single repo/product.
- Goal: get an agent working with your local workflow ASAP.
- Example harness/agent options mentioned:
-
Step 2 (this weekend): start your library
- Build one folder of Markdown files.
- Export notes and (if possible) email.
- For each:
- project you’re working on
- person you work with
- Create one page that captures what you actually know:
- what you’re building together
- what they care about
- what you owe them
- what they said last time
- Emphasis:
- models don’t have this; it exists in your head
- agents become valuable when they answer using your context instead of the internet
-
Step 3: write your first skill file
- Choose the task you do every week that you hate the most (e.g., expense reports, meeting notes, weekly status updates, competitor research).
- Write plain-English instructions:
- explain the job as you would to a smart friend on their first day
- Allow the agent to try (even if it gets it wrong):
- correct it
- include rules, exceptions, and “oh and also” details
- Result: the skill file becomes an “employee” you can run.
-
Step 4: wire it up as a recurring job
- Convert the skill into scheduled automation, such as:
- “Every morning at 7:00, do this”
- “Every Friday, summarize that”
- Expected shift: work finishing while you slept changes your sense of what “work” and “time” mean.
- Convert the skill into scheduled automation, such as:
-
Step 5 (discipline for compounding): never do one-off work
- Common mistake: run one agent task, then throw away the context/output.
- Instead, at the end of each task:
- have the agent skillify what it did (turn it into a reusable skill file)
- If you have to ask for something twice, you “failed” (YC-style maxim).
- Goal: knowledge becomes real memory (skills), not transient execution.
What progress should look like (time horizons given)
- Week 1: it’s “a toy”
- library thin; skills clumsy; you’re fixing more than saving
- Week 4: the “flywheel catches”
- agent answers using your context
- morning job produces something you actually read
- you write additional skill files because earlier ones worked
- Week 12: you have a functioning library + many skills
- a dozen skill files cover recurring week parts
- a small set of tools others ask to borrow (“which in this room is called a startup”)
Guardrails / hygiene requirement (important caveat)
A brain without curation is a garbage dump that retrieves confidently wrong facts.
Include:
- provenance for facts
- contradiction checks
- pruning via a “librarian” role
- treat the system as production infrastructure
