At the intersection of light and matter, physicists have demonstrated that electrons moving through semiconductors can be steered by two precisely tuned lasers rather than by conventional electric fields — a finding that quietly rewrites one of the foundational assumptions of electronics. The technique, dubbed an 'electron lighthouse,' does not merely refine an existing method; it opens an entirely different category of control, one in which light becomes a direct participant in the governance of charge. In the longer arc of technological history, this is the kind of proof-of-concept that tend
