Are our personal AI agents holding us hostage?

The author argues that personal AI agents like Grok Bot, Meta Muse, and Claude Code accumulate valuable memories about users that create lock-in, since exporting or importing memory is at best a one-time snapshot that forks rather than moves it. He describes self-hosting gBrain as a maintenance nightmare and suggests a better second brain would sit outside any single agent, readable and writable by all, so memory belongs to the user. Until then, he says, we remain willing hostages.
