The Second Machine Age (A Review)

Driveless cars, humanoid robots, 3D printers and the Internet of Things are just a few of the many technological developments that are increasingly converting science fiction into everyday reality. A recent book The Second Machine Age’ by Erik Brynjolfsson and Andrew McAfee argues that as extraordinary as these changes are, these are merely warm-up acts of a broader 'second machine age' that is already transforming us and is poised to sweep us off our feet in the near future!

The first machine age was characterized by muscle power epitomized by the steam engine and its descendants. In the second machine age, computers and other digital advances are increasing use of our brains, enabling us to understand and shape our environments. This is vast and unprecedented boost to mental power means that we are at an “inflection point” in the history of economies and societies. Crucially it is an inflection point in the right direction - bounty instead of scarcity, freedom instead of constraint. 

Three forces that are allegedly driving this new technological leap: exponential growth in computing power; growth in digitisation ; and, rapid innovation. The authors particularly believe that increases in Artificial Inteligence (AI) and ICT is accelerating, with the consequential impact of improving our health, labour productivity, economic prosperity and giving us a greater voice in the democratic process.

However, these drastic changes will also bring its own challenges and choices for individuals and governments. In particular, there is need for greater effort to deal with the inevitable rise in income inequality associated with technological change, which has largely shifted value from labour to capital. It turns out technological change does not lift all boats because of a complex relationship between economic power and political power, coupled with the the prevalence of in elastic demand and negative aspects of globalisation. 

The danger is that faced with rising inequality governments may respond with a Luddite approach. The authors believe a better solution is to actively explore ways in which governments can encourage the bounty of the second machine age while working to reduce or mitigate the harmful effects of income inequality. In the short term, it  means encouraging technology to race ahead while ensuring that as few people as possible are left behind. This can be achieved by growing the economy through basic economics 101 ideas. In the long term, focus should be placed on moving towards rebalancing the tax system to deal with inequality and unemployment.

The arguments are broadly persuasive particularly in relation to the interaction between technological progress and inequality. The authors insights around the the role of network economies play in explaining many manifestations of inequality are particularly insightful. As they note, each time a market becomes digital and networked, “winner-take-all economics” become a little more compelling. For example, executive pay is increasingly higher because direct management via digital technologies makes a good manager more valuable than in earlier times when managers had diffuse control via long chains of subordinates, or when they could only affect a smaller scale of activities.

The book also provides some interesting recommendations on how individuals and governments should seek to positively harness the second machine age. Individuals are advised to “seek to be an indispensable complement to something that’s getting cheap and plentiful”. Governments are encouraged to think innovatively about policies that help maintain technological growth whilst minimising the costs of inequality, though ideas such as : implementing a  negative income tax that combines a guaranteed minimum income with an incentive to work; and,  raising more revenue by increasing marginal tax rates on the highest income earners, for instance by introducing new tax brackets at higher levels.

Like most books, there are several instances where loose drafting and less rigor limits its potency. The authors are particularly prone, in their exuberance, to make sweeping statements that aren't always backed up by data. For example, they claim that “billions of people will soon have a printing press, reference library, school, and computer all at their fingertips”. Except we are not told whether these billions include people in a remote village in Eastern DRC. Unfortunately, these claims highlights another general weakness : this is a very American-centric offering that seems to pay little attention to a wider global evidence. There is little discussion on how technological change would impact cross country inequality and possible geopolitical relationship and global security, apart from the passing mention of the possibility of increased automation in the developing world. Quite ironic for a book that is heralding global change!

Readers will also not be surprised to learn that the authors’ worldview is highly naturalistic. They not only believe that “nature built us” but also that we are our best hope because the technology we have spawned such as, “Artificial intelligence will not just improve lives; it will also save [us]”. As they say later on, “there is no better resource for improving the world and bettering the state of humanity than the world’s humans—all 7.1 billion of us”. As followers of Jesus we naturally hold that only Jesus is the hope of the world, and our use of technology is better anchored in biblical values that do not shift like shadows. Man is certainly a poor saviour!

Despite these weaknesses, the book is certainly well worth a read. There are plenty of important issues discussed, and though many of recommendations are common sense, experience teaches us that sense isn't always so common, especially within governments.

The Christian and Technology, A Review

The central argument of John Fresko’s  The Christian  and Technology  is that technology is a double-edged sword that requires cautious and intentional use. Continuous uncritical use of technology erodes hunger for the Word of God, makes us self-centred and turns our useful devices into idols. The book intends to promote proper use of technology by encouraging us to dig into our hearts to see whether Christ so fills us that nothing can drag us away from him. Fresko believes there is no need for us to flee from technology or become Luddites because technology is value neutral. It is not in of itself good or bad. Instead, we must focus on carefully evaluating how we think about and use technology. This necessarily requires us  not only to understand the relevant technology, but also understand ourselves. A key part of this is recognising that we struggle with technology because we lack contentment in Christ. The book explores explores six different technologies. I think the most fascina

I am what I am by Gloria Gaynor

Beverly Knight closed the opening ceremony of the Paralympics with what has been dubbed the signature tune of the Paralympics. I had no idea Ms Knight is still in the singing business. And clearly going by the raving reviews she will continue to be around. One media source says her performance was so electric that "there wasn’t a dry eye to be seen as she sang the lyrics to the song and people even watching at home felt the passion in her words" . The song was Gloria Gaynor's I am what I am . Clearly not written by Gloria Gaynor but certainly musically owned and popularized by her. It opens triumphantly: I am what I am / I am my own special creation / So come take a look / Give me the hook or the ovation / It's my world that I want to have a little pride in / My world and it's not a place I have to hide in / Life's not worth a damn till you can say I am what I am The words “I am what I am” echo over ten times in the song. A bold declaration that she

Today I Learned

The puritan John Miles (1621-1683)   founded the first Baptist Church in Wales. He then emigrated to America shortly after the Act of Uniformity (1662) when 2,000 ministers were ejected from the Established Church. With a large proportion of his church, Miles settled at a new Swansea, about ten miles from Providence in Rhode Island. The church grew in face of persistent opposition.   Once, when Miles was brought before the  magistrates on some charge, he asked for a Bible. He then quoted Job 19:28 - Ye should say, Why persecute we him, seeing the root of the matter is found in me ? (KJV). He stopped there and sat down. The court was so convicted by the content and context of the passage that their cruelty gave way to kindness. ( Source : An Introduction to the Baptists, Erroll Hulse)
