The Combination Gap
Most hard problems in industry are not unsolved because the individual technologies don't exist — they're unsolved because no one has combined the right ones yet. An AR overlay is trivial. An IoT sensor network is trivial. Connecting live sensor state to a technician's field of view in real time — that requires both, plus the integration thinking that most firms don't have.
What this means in practice: We start every project by mapping which disciplines are in the room and which are missing. The gap between what exists and what's needed is usually a combination problem, not an invention problem.
