Under feudalism, the overlord would grant so-called fiefs to subordinates called vassals. These fiefs gave the vassals the formal right to exploit economically a part of the overlord’s realm — to plant crops on it, for example, or graze cattle — in exchange for a portion of the produce. The overlord would then unleash his sheriff to police the fief’s operation and collect what he was owed.

And then the overlords started selling the vassals Teslas in which

every circuit is wired into the cloud. Besides giving Tesla the power to switch off one of its cars remotely, if for instance the driver fails to service it as the company wishes, merely by driving around Tesla owners are uploading real-time information (including what music they are listening to) that enriches the company’s cloud-based capital.
