3 things that didn’t make the 10 Breakthrough Technologies of 2025 list
Next month, MIT Technology Review will unveil the 2025 list of 10 Breakthrough Technologies. Every year, our newsroom looks across the fields we cover for technologies that are having a true breakthrough moment. This annual package highlights the technologies that we think matter most right now.
In the meantime, here are three technologies that we considered including on the 2025 list but ultimately decided to leave off. And although these nominees didn’t make the cut this year, they’re still worth keeping an eye on. Read the full story.
