I thought that it was just me with the strange feeling like I am being listened too. Really disconcerting that instead they are capturing images. This is a worry on multiple levels. That any semblance of privacy has seemingly left the building, but also the waste associated with collecting such data.
I am reminded of the discussion of a big data tax mentioned in Sabeel Rahman’s post The New Octopus. James Bridle also talks about the ‘Age of the Image’ in the New Dark Age:

As digital culture becomes faster, higher bandwidth, and more image-based, it also becomes more costly and destructive – both literally and figuratively. It requires more input and energy, and affirms the supremacy of the image – the visual representation of data – as the representation of the world.
