Abstract
What's really happening when Claude's memory doesn't know what you told ChatGPT and your phone app doesn't share context with your coding agent? The common story is that AI memory is getting better—but the reality is more interesting when every platform has built a walled garden designed to create lock-in.
Highlights
- In this video, I share the inside scoop on why the architecture of agent-readable memory matters more than any individual tool:
- Why your Notion workspace is beautiful for humans and useless for agents that search by meaning
- How a Postgres database with vector embeddings runs for 10-30 cents a month
- What MCP servers enable when one brain connects to every AI you touch
- Where the compounding advantage lives for people who stop re-explaining themselves For anyone watching the agent revolution go mainstream, the gap between starting from zero and starting with six months of accumulated context is the career gap of this decade.
