Dear Editors, Always keen to consider a diversity of viewpoints on complex topics, I was excited to read Paul Krugman's perspective on Bitcoin and other digital currencies underpinned by open blockchains. I do not know Dr Krugman's work well, but I understand that he is a very strong establishmentarian, deeply embedded in the prevailing economic mindframe. And so I was disappointed, but not surprised, at his flippant and condescending disregard for the nascent technology that we are early in the process of discovering. Dr Krugman can be forgiven. Why fix what isn't broken? Why overcomplicate things? Why waste effort understanding what is fundamentally a new way to trust people? Why explore a digitally native form of one of the most precious things that make us human - money? I am a millennial - I do not have a strong economics background, and only have a basic grasp of how the global financial system functions. But more and more I tend to think that what we have is not working. Despite our ability to produce more than enough, human suffering persists on vast scales. Legions of the most intelligent people on Earth spend their time designing better ways to capture value, rather than create it - whether that's by finding minute inefficiencies in markets or conceiving more effective ways to exploit our attention. And while I do value financial stability (which is the raison d'etat for most central banks), something about the idea of the "an infinite amount of cash at the Federal Reserve" seems to undermine the entire premise of what money is. The spaces we occupy affect the quality and tone of our interactions. This is true of digital spaces as much as physical ones. It is becoming clear that money and finance are primarily information technologies - Dr Krugman's dismissal of cryptocurrencies shows that he fails to grasp that they are part and parcel of a potent new computing paradigm that is consciously re-architecting our digital spaces so they can better support people and society. Your newspaper, and Dr Krugman himself, very often criticizes a system optimized for the elite at the expense of the many. How can you so casually write off the first true alternative to the incumbent financial system, which plays an outsized role in perpetuating these inequalities, that we have seen emerge in generations, perhaps in history?
