I want to introduce a concept I’ll be coming back to throughout this blog: Personal Data Sovereignty, or PDS. It’s the idea that individuals can and should have meaningful control over where their data lives, who can access it, and what happens to it. Not as a legal right, as something you actually build.

If you’ve been reading this blog for a while, some of what follows will look familiar. I’ve written about the network setup, the GPU server, the second brain, the AI inference stack. This post isn’t about new technical ground, it’s more philosophical. PDS is the concept I’ve been building toward without naming it directly, and I wanted to put it in one place before the series goes any further.
