On the longest of our long weekends, it’s good to have something different to think about. Try this. Could it be that the information revolution – big tech, big data, the internet and social media – is changing how the economy works in ways we’ve yet to understand and won’t like?

The world abounds with economists repeating their conventional wisdom about how the economy works and will keep on working. But one economist politician thinks that digitisation is changing the economy in ways that could lead us back to a new kind of feudalism.

He is Yanis Varoufakis, who lectured at Sydney University for some years before returning to Greece and briefly becoming its finance minister. He visited Australia earlier this month as a guest of the Australia Institute.

In the Middle Ages, feudalism was a system of reciprocal military and economic obligations running from the king to his land-owning lords, whose vassals managed their land worked by serfs.

In Varoufakis’s dystopian vision, the digital revolution, led by a few big technology companies – Meta (Facebook), Alphabet (Google), Apple, Amazon and Microsoft – is turning capitalism into “technofeudalism”. Hence the title of his book, Technofeudalism: What Killed Capitalism.

In the internet’s initial phase, it was characterised by open protocols and decentralised networking, focused on information sharing and communication.

Now, however, it has evolved towards more commercialised, centralised services, including social media, e-commerce and cloud computing. His metaphor for the changed parts of the economy is the “cloud”.

The capitalists – owners of physical capital - are being replaced by “cloudalists”: individuals or businesses that control the major digital platforms (such as the Facebook, Google and Twitter sites) and related infrastructure, which allows them to extract “cloud rent” from the consumers and businesses using their platforms.
