"Visualize a scenario where a Roomba vacuum cleaner attempts to clean the hall of a university, but faces an overwhelming task. The dirt and clutter prove to be too much for it, and its small size makes it seem insignificant in the face of the daunting workload. Students pass by, murmuring to each other about the Roomba's inefficiency and lamenting the neglected state of the hall. The Roomba struggles to keep pace, but its efforts seem futile as chaos continues to accumulate around it".
