The Download: blended meat, restored sight, and the agentic web
摘要

本期通讯关注三项技术进展:一是初创公司Joyn等推出将植物蛋白与真肉混合的“混合肉”产品,试图降低红肉消费;二是PRIMA系统通过视网膜植入与摄像眼镜结合,帮助地图状萎缩患者恢复部分视力,超八成受训者恢复阅读等能力;三是AI代理正推动“代理型网络”成形,可处理收件箱、购物等事务,或深刻改变互联网形态。

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

These startups hope “blended” food will cut our appetite for red meat 

In the fall of 2025, Jeff Dodge served hungry students steaming marinara sauce and meatballs. The students loved them: 92% of those who tried them wanted them on the menu. Few could guess that mushrooms had been mixed into the meat.

Dodge was testing a new product called 50/Cut from the company Joyn. The blend of seemingly simple ingredients—available as meatballs, burgers, and ground meat—could help solve one of the biggest challenges of the climate crisis: getting people to eat less meat, particularly beef.

Joyn is among a wave of startups creating “blended meat,” which combines plant proteins with the real deal. The logic: The best meat replacement is … better meat.

Get a taste of the startups betting on greener beef.

This implant can restore sight for patients with macular degeneration

More than 5 million people have an advanced form of age-related macular degeneration (AMD) called geographic atrophy, in which retinal cells die off. Until now, no treatment could restore their vision. A system called PRIMA changes that.

It combines a retinal implant with camera-equipped eyeglasses to improve sight in patients who develop a blind spot in the middle of their vision. After training sessions, more than 80% of recipients could read, do crosswords, and use their phones.

Find out how the sight-restoring implant works.

MIT Technology Review Narrated: The agentic web is here

In 2001, a decade after inventing the World Wide Web, Tim Berners-Lee articulated a new vision: an internet navigated by autonomous software agents that address our every need, without requiring us to muck about with browsers and search engines ourselves.

At the time, the idea seemed far-fetched. But a quarter-century on, AI agents are beginning to make it a reality. They can triage your inbox, do your grocery shopping, and even access your bank accounts.

This new era is being called the agentic web, and it will inevitably transform the internet. Whether the human web survives this transition is anyone’s guess.

This is our latest story to become an MIT Technology Review Narrated podcast, which we publish each week on Spotify and Apple Podcasts. Just navigate to MIT Technology Review Narrated on either platform, and follow us to get all our new content as it’s released.

One more thing


Want to understand the current state of AI? Check out these charts.

If you’re following AI news, you’re probably getting whiplash. AI is a gold rush. AI is a bubble. AI is taking your job. AI can’t even read a clock. Stanford’s 2026 AI Index—the field’s annual report card—cuts through the noise. 

The data reveals a technology evolving faster than we can manage. From the China-US rivalry and model breakthroughs to public sentiment and the impact on jobs, here are the index’s key findings on the state of AI today.
