“Software Is Eating the World,” Fifteen Years On

On August 20, 2011, the Wall Street Journal published an essay that became the operating thesis of a generation of founders and investors. Marc Andreessen — co-founder and general partner of the venture firm Andreessen Horowitz, which had backed Facebook, Groupon, Skype, Twitter, Zynga, and Foursquare — argued that software was no longer a sector. It was the thing eating every sector. “In short,” he wrote, “software is eating the world.”

The essay’s claim was structural, not cyclical. Six decades into the computer revolution, four decades after the microprocessor, two decades into the modern internet, Andreessen argued that all the technology required to transform industries through software finally worked — broadband, the cloud, mobile. His exhibits were the incumbents being devoured: “Perhaps the single most dramatic example of this phenomenon of software eating a traditional business is the suicide of Borders and corresponding rise of Amazon,” he wrote, noting that in 2001 Borders had handed its online business to Amazon on the theory that online book sales were non-strategic. Oops.

The essay landed amid bubble anxiety — Facebook and Twitter’s soaring private valuations had Silicon Valley asking whether Webvan and Pets.com were being repriced — and Andreessen’s answer was that the skeptics were fighting the last war. The new internet companies, he argued, were building real, high-growth, high-margin, defensible businesses. History’s verdict on that paragraph has been generous.

What he got right

Fifteen years on, the core prediction reads less like a forecast than a description. Industry after industry was rebuilt by software-native entrants rather than by incumbents learning software: retail, media, music, taxis, hotels, finance, recruiting. The mechanism Andreessen named — every company becoming a software company, whether it knew it or not — became the default strategy of the 2010s. Even the holdouts now describe themselves in his vocabulary.

The blind spot

The essay contained one assumption nobody questioned in 2011: that software would remain the apex predator — the disruptor, never the disrupted. The 2020s have tested that assumption. Artificial intelligence is now doing to software companies what software did to Borders: automating their core work, collapsing their margins, and forcing the question Andreessen never had to ask — what eats the eater? The thesis survived its first fifteen years. Its second act is about whether the predator becomes prey. That is a story this magazine intends to follow closely.
