The idea
The field still cannot build an agent acting rationally in indefinitely long, partially observable worlds shared with other autonomous agents — the cell where every dimension is hard.
In practice
Kitchens, workplaces, and cities live in that corner; deployed systems live nearby.
Where people slip
Partial observability hurts most, by the field's own account — the open corner is why the field is not a museum.
