After 1,800 Years Much the Same, World Output Grew More Than 100-Fold
Investor Raviraj Jain argues that steam, electricity, computing, and AI did not just follow each other, each one made the next arrive faster.

Raviraj Jain, an investor at the venture firm Lightspeed, was trying to explain where economic progress really comes from. He pointed to a chart tracking everything the world produced across 2,000 years. His point was that each big breakthrough speeds the next one, so the gaps between them keep shrinking.
His line was simple. As Jain put it, “most of the progress in the world happens at the frontiers.”
By frontier, he meant building technology never built before, using science in ways never tried, or bringing cutting edge tools into old industries that people had written off as never changing.
The chart was his evidence. As Jain put it, “human life was pretty much the same” for the first 1,800 years. He added that in 1800 people were “living basically the same life as old Romans did.” In just the last 200 years, he said, global production grew more than 100-fold. He ties that surge to a chain of major breakthroughs.
That chain started, in his telling, with steam engines and rails. Steam made it possible to manufacture goods in large volumes, and railroads moved those goods and people. Within about five decades, Jain said, electricity arrived and changed the world again. Then came cars and autos, powered by widely available oil, and about four decades after that, computing. A normal handheld calculator today, Jain said, has more power than the computer used in the Apollo 11 mission in the 1960s. In 1995, the internet became the next frontier, followed now by artificial intelligence.
In his account, electricity enabled computing, computing enabled the internet, and those earlier breakthroughs together enabled AI. Each frontier speeds up the next, so the gaps between them keep shrinking.
That compounding, in his view, is why several new frontiers are now emerging at the same time.
Questions people ask
Was life really about the same in 1800 as in Roman times?
In broad terms, yes. Economic historians estimate that average income and life expectancy changed very slowly between ancient Rome and about 1800, with most people working in farming and living about as long as their distant ancestors. Sustained growth in output per person took off with industrialization, first in Britain and then much more widely.
Why would one invention make the next one come faster?
New tools lower the cost of the next discovery. Cheap electricity made computing practical, computing made the internet possible, and the internet supplied the data and distribution that modern AI needed. Better instruments, faster communication, and larger markets also let ideas spread and improve more quickly.
Does that mean growth will keep accelerating?
Jain believes so, and argues we are entering an era when several frontiers advance at once because they build on one another. Many economists agree that innovation can compound, although they also warn that progress is not automatic and can be slowed by energy limits, regulation, war, or failure to spread new tools widely.
