Charts of the Week: Software Ate the World
Short summary
The article traces tech’s rise from cloud in 2016 to today, showing software firms now rival entire economies in market cap. It then draws parallels to 19th-century railroads, explores AI’s potential to reshape corporate hierarchies, notes stablecoins shifting toward payments, and examines plunging trust in mass media among younger generations.
- The ten largest public companies by market cap now exceed the combined GDP of the G7 (excluding the US), achieved within roughly a decade of cloud computing's rise.
- Railroads once commanded up to 63% market share and forced the invention of modern corporate hierarchy; some argue AI could similarly flatten management structures today.
- Stripping out speculative and treasury flows, stablecoins generated $350–550 billion in genuine payment transactions last year, with consumer usage growing fast.
- Trust in mass media has collapsed from 72% in 1975 to 28% in 2025, with young Americans increasingly relying on social platforms instead.
Full summary
Tech companies now tower over the traditional economy. The ten largest public firms by market cap outstrip the combined GDP of the G7 (ex-US), a milestone they reached barely a decade after cloud computing took off around 2016. Back in 2015, those top ten accounted for just a fraction of global output; today they make up roughly twice the share of the S&P’s overall market value and drive more than 60% of its earnings growth since 2023. Only three names from the pre-2015 list remain, and only Microsoft survives from the decade before that—a reminder that betting on the old guard in tech would have massively undershot reality.
A century ago, railroads held a larger market share—up to 63%—than tech does now, and their real impact was to spawn entire new industries and reshape corporate life. Railroads forced companies to invent middle management, complex org charts and multi-divisional hierarchies. Today, some leaders argue AI could do the same for our 170-year-old management model: replacing layered oversight with automated decision-systems and pushing humans toward customer-facing roles. If that plays out, firms will look very different, more networked and lean.
On the financial front, stablecoins are shifting from speculative trading to real-world payments. Stripping out exchange flows and internal treasury moves reveals $350–550 billion in genuine payment transfers last year. Business-to-business transactions dominate the volume, but consumer use (B2C, C2B) is growing fast, signaling stablecoins inching toward everyday commerce. Meanwhile, trust in mass media has sunk to 28% in 2025, down from 72% in 1975. Young Americans, in particular, now lean heavily on social platforms for news, widening a sharp generational divide in both trust and consumption.
