    Dr Doom and Mr Ethereum debate crypto

    Cryptocurrencies By Leonid Bershidsky12 October 2018
    Facebook Twitter LinkedIn WhatsApp Telegram Email

    Economist Nouriel Roubini, nicknamed Dr Doom for predicting the most recent global financial crisis, has crossed swords with cryptocurrency guru and ethereum founder Vitalik Buterin. In the epic battle of words, both are right about some things, and neither is quite wrong. Theirs is a fundamental, and philosophical, conflict.

    It started with Roubini’s testimony before the US senate’s banking committee on Wednesday. The New York University professor, who has long disparaged virtual currencies and the blockchain technology behind them, delivered a particularly stinging indictment of the industry.

    “Scammers, swindlers, criminals, charlatans, insider whales and carnival barkers (all conflicted insiders) tapped into clueless retail investors’ Fomo (“fear of missing out”), and took them for a ride selling them and dumping on them scammy, crappy assets at the peak that then went into a bust and crash — in a matter of months — like you have not seen in any history of financial bubbles,” said Roubini, about the crypto phenomenon of the past two years.

    Roubini’s testimony was a comprehensive, tersely argued takedown of crypto. But it was also full of personal attacks on Buterin

    He made all the familiar arguments about cryptocurrencies: that they have no intrinsic value; that they impose transaction costs that are too high for small payments, making them useless as currencies; and that they use up too much energy to generate. He warned that bitcoin, the most popular cryptocurrency, was deflationary in nature because of its finite supply (in a growing economy, that means prices denominated in bitcoin cannot but fall) and that most of the other virtual currencies “have an arbitrary supply-generation mechanism that is worse than any fiat currency”.

    Roubini pointed to research showing that almost four-fifths of all initial coin offerings have been outright scams. He argued that the crypto economy was concentrated in dodgy jurisdictions such as China and Russia, and that it created a wealth inequality “greater than that of Kim Jong-un land”.

    As for the blockchain, it isn’t a revolutionary technology, the economist said, because the financial solutions based on it are not scaleable, truly decentralised or secure.

    Takedown

    In short, Roubini’s testimony was a comprehensive, tersely argued takedown of crypto. But it was also full of personal attacks on Buterin for his failure to deliver a scaleable system he’s promised since 2013, and even for the allegedly buggy code of his ethereum platform.

    Buterin was quick to counter with an attack on Roubini’s credentials. “I officially predict a financial crisis some time between now and 2021,” he tweeted. “Not because I have any special knowledge or even actually think that, but so that I can have a ~25% (or whatever) chance of later being publicly acclaimed as ‘a guru who predicted the last financial crisis’.”

    This started off a debate between him and Roubini in several Twitter threads which can best be described as an economist’s conversation with a technologist; it’s not quite as bad talking over each other in two different languages, but it’s close. For example, Roubini attacked sharding — a technology meant to speed up transactions recorded on a blockchain — as “vapourware”; crypto enthusiasts quickly responded that Google used a version of it in cloud computing. On the other hand, Buterin had no clear answer to Roubini’s arguments concerning the immediate uselessness of crypto as a financial technology; all he could say, essentially, was that technological problems were in the process of being resolved.

    For the engineer, the failures are merely inputs, and the scams are irrelevant

    The exchanges reflect a fundamental difference in worldview. The economist looks at the present state of affairs, and sees a familiar phenomenon: a hype-based bubble without workable fundamentals, and a highly imperfect technology that, at the moment, works worse than other solutions. (Roubini’s examples include fintech leaders such as PayPal and Alipay.) The engineer sees a problem worth solving — in this case, removing a central approving and certifying authority from financial transactions, and all kinds of contracts — and works on solutions. For the economist, the current failure rate is important, and the sheer number of scams surrounding a particular technology triggers red alarms. For the engineer, the failures are merely inputs, and the scams are irrelevant.

    In this particular case, Roubini resorted to an ad hominem attack, too, but Buterin had a quick (and calm) rebuttal ready. Even as the founder of the second biggest cryptocurrency after bitcoin, he’s not a paper billionaire, getting wealthy off the crypto hype, and, thanks to the blockchain, his transactions are relatively transparent.

    Philosophical difference

    This, however, isn’t important. In our increasingly tech-dominated world, what matters is the philosophical difference. Do we want to stick with technology sufficient to run the world as we know it, just a bit more efficiently; or are we okay with technology that tries to change the nature of our interactions? That’s a question we need to ask more and more often — about gene editing, self-driving vehicles, communication and commerce without privacy and, yes, potential applications of the blockchain.

    I’m with the retrogrades on most of this, but I also understand and respect the engineers’ refusal to recognise existing boundaries as red lines.

    Even if the crypto market implodes, as some predict, the engineers will keep working on the technology. A second coming should not be ruled out. There are plenty of precedents: electric cars, tablet computers, virtual reality. The smart money isn’t on the hype, it’s on the research and development.  — (c) 2018 Bloomberg LP
