What insights does the double-slit experiment provide?

I'm teaching an advanced quantum foundations course, and I want to move the discussion past the standard textbook narrative. The experiment seems to be a gateway to discussions about measurement, decoherence, and interpretations. What does it really force us to confront about the role of the observer or the nature of quantum objects before measurement?

Having debated this in countless seminars, I'd say its deepest insight is the context-dependence of physical reality. The experiment shows that an electron isn't a particle or a wave. Its "state" is a set of potentialities, and the physical context the entire experimental arrangement, including what we choose to measure actualizes one property over another. This isn't just about duality; it's a demonstration that properties like "path" aren't inherent but are created by the specific question we ask. It forces us to confront that the universe at a fundamental level is about relationships and information, not isolated objects with fixed attributes.
