The Second Machine Age

Erik Brynjolfsson and Andrew McAfee · 2014

More capability does not mean evenly shared gains.

Big Idea

The authors argue that digital technologies can create enormous economic value while leaving the benefits distributed very unevenly.

Exponential progress

They describe rapid improvements in computing that can make earlier expectations obsolete.

Digital combinations

Existing tools and information can be recombined into further products and capabilities.

Bounty and spread

Total abundance can grow while gaps between people and firms also widen.

Race with machines

Complementing machine capabilities is different from assuming every human skill must compete directly with automation.

Choices shape the outcome

Education and institutions affect distribution; the book’s 2014 forecasts should not be mistaken for guaranteed present-day outcomes.

Khizooo Take

For a new tool, ask both what it makes possible and who can realistically benefit from it.

Remember

Progress and shared prosperity are separate questions.
