Yes, that metaphor is full of potential. It is true.
From the very beginning, the data scientists at Google who were inventing surveillance capitalism celebrated in their written patents and in their published research the fact that they could hunt and capture behavioural surplus without users ever being aware of these backstage operations. Surveillance was baked into the DNA of this economic logic and essential to its strange form of value creation, so it's with that kind of sobriety and gravitas that it is called “surveillance capitalism”, because without the surveillance piece, it cannot exist.
