## Quote — verbatim

> Most of the data, if you look at it, is in devices they're owned by people, and it's extremely hard to get — the more sensitive the data, the harder it gets... I personally wouldn't be comfortable giving my medical data or my diagnosis to a system that doesn't guarantee the privacy... and decentralization is an answer.

## Context — site annotation, not spoken

Asked whether data remains AI's limiting factor; Greg's data-sovereignty thesis — sensitive data (medical, financial) can only be tapped for training if privacy is guaranteed, which he argues centralized systems can't do. Quote spans into the next caption block.
