An adult is someone who looks both ways before crossing the street, and then gets hit by an airplane.
Over the past few weeks, we have had our lives disrupted. I want to take this opportunity to discuss one way to think about your experience from an AI perspective. Specifically, I want to consider the Planning Domain Definition Language (PDDL) model of planning. Here is the shopping plan we looked at earlier.
PlanningProblem( init='At(Home) & Sells(SM, Milk) & Sells(SM, Banana) & Sells(HW, Drill)', goals='Have(Milk) & Have(Banana) & Have(Drill)', actions=[Action('Buy(x, store)', precond='At(store) & Sells(store, x)', effect='Have(x)'), Action('Go(x, y)', precond='At(x)', effect='At(y) & ~At(x)')])How would you have to modify this plan to achieve the goal: Have(N95FaceMask)?
The PDDL plan would not work because its assumptions are no longer valid. This is true for much of our lives now. The goals and plans and actions that we took for granted are often no longer valid. We need to revisit our assumptions, abandon our old goals, formulate new plans.
I invite you to think about this in the coming weeks. What plans no longer work? How do you cope? How do you recompute? How would you program a robot to revise its plans? How would a robot benefit from having relationships with other agents? This strikes me as a good take home exam question.
