As excitement over Bitcoin as a new form of currency has met with strong pushback from the economics world, the smarter commentators have shifted focus to cryptocurrency as a new way to move money around on the Internet. But how would that really work? The first thing you hear in these discussions is that Bitcoin

It’s been interesting to see the debate over Bitcoin start with currency, move on to payments, and now there are rumblings that its real use isn’t for either. Rather, cryptocurrency could be a way of marking digital goods as unique, making them in effect rival. Technology Review explains: Or take digital art. Larry Smith, a

Recall the classic utilitarian morality puzzle (via Wikipedia): There is a runaway trolley barrelling down the railway tracks. Ahead, on the tracks, there are five people tied up and unable to move. The trolley is headed straight for them. You are standing some distance off in the train yard, next to a lever. If you

It’s no secret that I’m a bit obsessive about my news habits and filters, manifested most obviously in constant tweaking of my RSS feeds but also in who I follow on Twitter, what email newsletters I allow into my inbox, etc. The challenge in these adjustments is always to strike a balance between drinking from

How will humans add value to algorithms?

Last month, I wrote a piece at HBR about how humans and algorithms will collaborate, based on the writings of Tyler Cowen and Andrew McAfee. The central tension was whether that collaboration would be set up such that algorithms were providing an input for humans to make decisions, or whether human reasoning would be the

iPhones and Income: Does Technology Change the Middle Class Stagnation Story?

One of the most common responses to my post on middle class incomes was to point out the role of technological progress. If the average American family went back in time to 1989, I wrote, they’d make just as much money but work longer fewer hours to do it. But, some responded, they wouldn’t have iPhones.

Middle Class Incomes: Up, Flat, or Down?

Depending on who you ask, the incomes of the American middle class over the past few decades have either a) risen only a little b) stagnated, i.e. stayed flat or c) declined. When President Obama declared in his State of the Union speech that family incomes had “barely budged” from 1979 to 2007, The Washington

The most intuitive way to structure a paywall with respect to premium content — like, say, a longform reported magazine piece or a Snowfall-style multimedia feature — is to offer the cheaper content for free and put the premium stuff behind the gate. I say intuitive simply because it costs you more to produce that stuff;

Average is Over, Robots, and the Minimum Income

I recently read Tyler Cowen’s latest book Average is Over, and I’d recommend it to anyone thinking about technology and the future of the economy. It’s a highly readable vision of what the coming age of ubiquitous intelligent machines will mean for workers and the economy. Here’s a bit from Chapter 1 that captures Cowen’s

Don't gamify healthcare -- gamify health

There was a piece in Fortune earlier this month with which I strongly disagreed, on the subject of healthcare, technology, and “gamification”. The post centers around a health tech hackathon and, I think, in dismissing the promise of gamification, misses one of the most promising aspects of health IT. Here’s the gist: Several months ago,
