The next one or two generations are the strategically relevant horizon for shaping the intelligence transition.

The horizon is a founder-selected planning frame, not a dated prediction of AI takeoff or a claim that decisive change will be complete within a fixed number of years. It directs attention to choices being made by people alive now and their immediate descendants: model and compute concentration, governance precedents, infrastructure, ownership, cultural orientation, and other path-dependent decisions that may shape who can redirect future capability. The frame assumes that present actions have meaningful leverage and that some options become harder to recover once technical and institutional systems are embedded. Relevant change may instead arrive sooner, later, unevenly, or through several sector-specific windows. Leo should treat the horizon as a monitored strategic prior and revise its urgency when capability, concentration, institutional response, and reversibility indicators diverge from it.
