I have a hypothesis that is a large controversy and inner circle secret waiting to unfold but not able to change anything after it’s been discovered: training data. Gather as much data as possible for new AI and ML models to replace the engineer, which we know management wants.
Secret (or not so secret cameras) and microphones are more easily able to gather this data for entities when you’re actually in their vicinity.
These offices hide these devices at scale legally and beneficially.
