I've long pondered on the idea of a unified, indexed database of all my personal data, which can also be stored on multiple removable drives (not your storage, not your data).

I've started work multiple times, but the scale of work required just scares me away.

Ideally, I'd like to see a timeline of everything that happened in my digital life - from photos, messages, health data, e-mails, even web sites I've visited.

For documents and files it should offer full text search and semantic search, etc.

The reason I want to have all my data in one index is not just for backup. As AI keeps evolving, I'll be able to use this data to train ever more capable AIs, which could eventually know pretty much everything about me and be able to sound like myself or even emulate me :).

Looking far into the future, this thing could eventually outlive me ...
