The Future We Were Promised
The 1979 Osborne Book of the Future promised moon bases by now, fusion power within 10 to 20 years, robot cars, and machine intelligence running the world. All framed as entirely benign. The Soviet bloc ran similar projections. Post-scarcity was the shared assumption: automation would free people to pursue hobbies while John Maynard Keynes’s 15-hour working week arrived on schedule.
Lewis’s son, born this century, flipped through that 1979 book and asked why books like it no longer exist. That question is the talk’s starting point.
The Future Was for a Minority
GPS, handheld computers, video calls, electronic money, two operational space stations. The technology arrived. But Henney and Lewis point out it arrived for a narrow slice of humanity. The O’Neill cylinder of the 1970s imagined all levels of society living in space. Elysium, the 2013 film, shows what actually happened: a gated community in orbit for the very rich while Earth decays below.
The Gini-coefficient gap widened. In 1975, the year 2000 felt exciting. In 2025, 2050 does not.
Why Automation Did Not Buy Us Free Time
Jevons Paradox: as efficiency rises, total consumption rises too. DeepSeek made tokens cheaper; token demand did not fall. A paper on weekly working hours found people who use GenAI more end up working two to four extra hours per week. David Graeber called the backfill “bullshit jobs.”
Agent-based models of capitalist exchange demonstrate the same pattern at scale. Start every agent with equal wealth, run random trades, and one agent ends up with everything every time. The Netherlands is close to the only modeled western democracy not trending toward an oligarchic phase transition.
The Metaverse as Cautionary Case Study
In 2021, Zuckerberg renamed Facebook and announced a metaverse where people could get together with friends, work, learn, play, shop, and create. We were already doing all of that. The metaverse offered the same things with “janky, headache-related graphics” and no legs.
Snow Crash coined the term metaverse in 1992 as a dystopia. Second Life built it in 2003 and briefly showed up in CSI episodes. The world took a different path: the web, chat apps, and COVID-era remote work delivered what the metaverse promised, without the headset.
Connectivity Is the Actual Driver
What actually shifted the world was connectivity, physical and social together. Undersea cables, satellite networks, fiber bandwidth, road freight routes, and rising mobile coverage compounded for decades. The modern car only makes sense on smooth roads; GPS only works because thousands of satellites are invisible overhead. We discount what we cannot see and underestimate what enables everything else.
Social connectivity followed. Dunbar’s number caps a person’s meaningful social group at around 150. Online networks stretched those slots across Norway, Germany, and everywhere else, amplifying fringe views by giving isolated individuals thousands of agreeing strangers.
How Change Actually Happens
China’s Tokamak reactor held nuclear fusion for 1000 continuous seconds in 2025, up from 500 seconds the previous record. Space elevator material science exists now; the gap is social willingness, not physics. Arthur C. Clarke: “We will do it when we stop laughing at the idea.” Artificial compute is approaching 10^17 MIPS, within one order of magnitude of all human brains combined.
The video phone arrived not from telephone companies building video phones but from chat apps adding cameras. Change is gradual, cumulative, and rarely comes from the direction the forecast pointed.

Key Takeaways
- The 20th century’s optimistic futures mostly arrived, but concentrated in a tiny minority rather than spreading universally.
- Jevons Paradox explains why GenAI, like every efficiency gain before it, makes workers log more hours, not fewer.
- Futures do not arrive by blueprint; they emerge from accumulated infrastructure and connectivity that nobody planned.
