For more than a decade, the most exciting technologies were the ones that weighed nothing. A model trained on a cluster in Nevada could generate a poem in Nairobi in milliseconds. A piece of code written in San Francisco could reshape how a billion people communicated, with no factories, no supply chains, no atoms moved at all. Software scaled to infinity and cost almost nothing to reproduce. It was seductive, and for a while, it seemed like the whole future would be made of it.
Then the World Economic Forum and Frontiers published their Top 10 Emerging Technologies of 2026, and the list tells a different story. Eight of the ten technologies act directly on physical systems. Not on screens. Not on feeds. On power grids, drug pipelines, food production, cooling systems, and the chemistry of forever chemicals in drinking water.
The list includes everything-to-grid energy systems that turn every electric vehicle and building into a node in a distributed battery network. Direct lithium extraction that pulls battery-grade material from salt flats in hours instead of months. Passive radiative cooling materials that reflect heat through the atmosphere and back into space, cooling buildings without consuming a watt of electricity. PFAS destruction — finally, a plausible way to break down the “forever chemicals” we engineered to be indestructible. Precision fermentation that brews food ingredients and medicines in tanks of genetically programmed microbes. Exosome drug delivery that hijacks the body’s own cellular packaging to carry therapies exactly where they need to go. Personalized mRNA cancer vaccines tailored to the mutational fingerprint of a single patient’s tumor. Quantum simulation for drug discovery. World models that learn physics from multimodal data. Lattice-based cryptography to harden our secrets against the quantum computers we know are coming.
Frederick Fenter, chief executive editor of Frontiers, put it plainly: “This year’s report marks a decisive shift — the technologies with the greatest impact are shifting from software towards the physical realm.”
I find this quietly moving. Not because software is finished — it isn’t, and AI is woven through nearly every entry on that list as an enabling layer. But because the center of gravity is moving. The problems that matter most now are problems of matter: how to cool a building without burning carbon, how to feed people without destroying topsoil, how to deliver medicine without poisoning the healthy tissue around it, how to store energy when the sun isn’t shining. These are old problems. They are problems our grandparents worried about. And they are problems that require touching the world — not just modeling it.
There is something almost humbling about it. For years the rhetoric was about disruption, about moving fast and breaking things, about the infinite malleability of bits. The physical world was stubborn and slow and regulated, an obstacle to the clean acceleration of software. Now it turns out that the physical world was where the real work always was. You can generate all the images you want, but you cannot generate a cooler planet. You can train a model on every scientific paper ever written, but someone still has to figure out how to extract lithium without draining an entire desert. You can simulate a protein fold, but the vaccine still has to be brewed, tested, shipped, and injected into an arm.
The report itself was compiled with AI — Frontiers used an AI-based workflow to screen more than 1,200 candidate technologies. There is a small irony there. The ghost in the machine, the weightless intelligence that was supposed to replace so much of what humans do, ends up being most useful as a tool for finding the technologies that will finally drag us back into contact with atoms and energy and biology. AI as a guide, not a destination.
Stephan Mergenthaler, managing director at the WEF, said the technologies “reveal new patterns across energy, medicine, and manufacturing that could challenge long-held assumptions about how we use technology to address some of the world’s most pressing challenges.” I think the long-held assumption being challenged is the idea that the most important technologies are the ones that live in the cloud. The cloud is still there. But the ground beneath it is where the interesting work is happening now.
I don’t know if this shift will last. Software has a way of swallowing attention. The next breakthrough in reasoning models or agentic AI might dominate the headlines again next month. But the WEF list is a signal, and signals matter. Capital follows them. Research follows them. The best young engineers, the ones who might have spent the last decade optimizing ad targeting algorithms, might look at this list and decide instead to work on cooling materials, or precision fermentation, or grid-scale storage. That would be a good thing. The weightless future was always a fantasy. The real future has mass, and temperature, and chemistry. It always did.
