DARPA's neural interface program went dark after Phase III. Germany just awarded the largest single research grant in EU history for passive BCI. Here is the documented timeline nobody is connecting.

Something shifted in defense neurotechnology around 2020 that has not received proportional public attention. DARPA's N3 program funded injectable magnetoelectric nanotransducers designed to cross the blood-brain barrier and provide bidirectional neural read/write without surgery. The program reached Phase III human trials in 2023. Then the public webpage was marked "complete" and went silent. DARPA stated it "does not operationalize technologies" and directed questions to the six research teams.
