On November 30, 2022, OpenAI released ChatGPT.
At the time it looked like a clever chatbot — fun to poke at, easy to dismiss. In hindsight, it may turn out to be one of those rare hinges in history: the day a new era quietly began. I’ve come to believe we will remember it as the opening of the Fourth Industrial Revolution — not steam, not electricity, not computing, but intelligence itself becoming something we can build, scale, and improve.
Why this one is different
The first three industrial revolutions each automated a kind of work. Steam and machinery extended our muscles; electricity extended them further and lit the world; computing extended our memory and our capacity to calculate. Every one of them still needed a human mind at the center — to decide, to design, to judge.
What changed on that November day is that the mind itself became something you can manufacture. Intelligence — the thing that sat at the center of all previous automation — is now an input you can buy, copy, and pour into a problem. That is a difference in kind, not degree.
It will arrive faster than the last three
Steam took the better part of a century to remake society; electricity, decades; the computer and the internet, a generation. Each of those ran on the physical timescale of building factories, stringing wires, laying cable.
This one runs on software. The distribution is already built — every phone, every browser, every API. When the bottleneck is a model weight rather than a power grid, diffusion happens in months, not decades. Most people are still calibrated to the old clock, and I think that is why the pace keeps surprising us.
There is no opting out
You can decline to use a technology; you cannot decline to live in the world it reshapes. When intelligence becomes cheap and abundant, it reprices everything downstream of it — what a job is worth, what a company is for, what a person needs to know. Sitting it out is not a neutral choice; it is a choice to be shaped by others’ decisions rather than your own.
So the only sensible response is to embrace the new era and help shape it — to build with these tools, to think hard about where they should and shouldn’t go, and to stay close enough to the frontier to have a say.
The takeaway
I don’t know exactly what the coming decades hold — nobody does. But I’m convinced the changes will be sweeping, that they will arrive faster than most expect, and that November 30, 2022 will be read as the first day of it. This blog is, in part, my attempt to watch that unfold up close and take notes.
