The U.S. Government Accountability Office has released its second annual science and technology horizon scan, and the selection is pointed: neural implants for human augmentation, general purpose robotics, and orbital debris remediation. Three technologies that share almost nothing on the surface — and almost everything underneath.

The report (GAO-26-108079) uses a STEER framework — Social, Technological, Environmental, Economic, Regulatory — to map not just what these technologies do but what conditions need to exist for them to matter. That framing is more honest than most tech forecasts. It treats innovation as a systemic outcome, not a product release event.
