10 Breakthrough Technologies 2026

10 BreakthroughTechnologies Our reporters and editors constantly debate which emerging technologies will define the future. Once a year, we take stock and share some educated guesses with our readers. Here are the advances that we think will drive progress or incite the most change—for better or worse—in the years ahead. Climate change and energy Sodium-ion batteries Sodium-ion batteries, made from abundant materials like salt, are emerging as a cheaper, safer alternative to lithium. Backed by major players and public investment, they’re poised to power grids and affordable EVs worldwide. artificial intelligence Generative coding AI coding tools are revolutionizing how we write, test, and deploy code, making it easier and faster to build sophisticated websites, games, and other applications than ever before. Just be sure to double-check what they come up with. climate change and energy Next-gen nuclear Nuclear power already provides steady electricity to grids around the world, without producing any greenhouse-gas emissions. New designs rely on alternative fuels and cooling systems or take up less space, which could get more reactors online faster. artificial intelligence AI companions Every day, millions of people interact with AI chatbots. Some of them form what feel like close, personal bonds with the bots. There’s mounting evidence that this can be dangerous, and politicians are finally waking up. biotechnology Base-edited baby When he was just seven months old, baby KJ became the first person to receive a personalized gene-editing treatment. A clinical trial is now planned, and bespoke gene-editing drugs could be approved within the next few years. biotechnology Gene resurrection Growing banks of gene information on extinct creatures are providing clues to new treatments and suggesting solutions to climate change—and may help save endangered species. artificial intelligence Mechanistic interpretability Nobody knows exactly how large language models work, which means we don’t have a clear idea of their limitations. But that’s changing: Clever research techniques are giving us the best glimpse yet of what’s really going on inside the black box. space Commercial space stations Space tourism may seem fanciful, but this might be the year paying customers can finally check into a room with a galactic view. The shiny new modules will also support research missions by scientists and space agencies. biotechnology Embryo scoring Screening embryos for genetic diseases is relatively common practice in fertility clinics today, and it can give potential parents some peace of mind. Now, though, new startups are making bold claims about using similar techniques to predict certain traits, including intelligence. artificial intelligence Hyperscale AI data centers The race for AI supremacy has supercharged data centers. Hyperscale AI data centers pack powerful computer chips into synchronized clusters that work like giant, high-speed supercomputers—sizzling hot, power-hungry behemoths pushing infrastructure to its limits.

Cast your vote before April 1, 2026. 10 Breakthrough Technologies About the List MIT Technology Review’s annual list of 10 Breakthrough Technologies aims to help our audience know which emerging technologies are really worth paying attention to right now. Our editors and reporters pitch advances that they think should make the list, and we discuss and debate the merits of each over the course of several months. We look for breakthroughs that will have a broad impact and make meaningful differences in our lives and work. We give equal consideration to those that we think will have a positive effect or bring negative consequences. Every year, we have to pass on many worthy candidates. Here’s what didn’t make the list this year. This is the 25th year we’ve produced this list. Predicting the future is tough and we don’t always get it right. Look back through our archives to see what’s worked out—and what hasn’t. Or read this special analysis by an MIT researcher about some of the flops.
