Our proposal to study the financial system as an ecosystem is sometimes criticized as 'abuse of vegetational concepts'. Interestingly enough BBC documentary maker Adam Curtis now argues the whole notion of the ecosystem is in fact a boomeranged metaphor.
In his documentary 'All Watched Over by Machines of Loving Grace', Curtis claims that the notion of the 'ecosystem' was, from the very beginning, based upon technological metaphors: the idea of nature as a complex machine. I hurry to emphasize that the next nature view goes exactly the other way around: the idea of complex machines as nature.
