Most neurotech approaches require opening the skull. @ARIA_research's £50m Massively Scalable Neurotechnologies program is asking the field whether high-performance neurotechnology can be delivered to the brain in a 30-minute outpatient procedure without transcranial surgery.

Sonalis, one of the teams funded by @ARIA_research, is working toward read/write of electrical signals anywhere in the brain without opening the skull.

I had an absolute blast chatting with @juanbenet about the future of neurotech.
For neurotech to reach everyone who needs it, we need treatments that are both more effective and dramatically easier to deliver. That’s the ambition behind the programmes I’m leading at @ARIA_research.
Juan is a super thoughtful host, and this is the deepest conversation I've had about my journey, what it means to lead ambitious R&D, and the future we could unlock if next-generation brain therapies can genuinely scale.
Episode 3 of my new podcast features Dr. Jacques Carolan (@JacquesCarolan), a founding Program Director at ARIA (@ARIA_research), the UK’s Advanced Research and Invention Agency. He directs two neurotech programs aimed at one of the most important opportunity spaces: developing tools and systems to interface, at scale, with the human brain.
One program is built on the idea that brain disorders are circuit problems, and funds tools to target those circuits with molecular precision across the whole brain. The other aims to deliver high-performance neurotech to the brain non-invasively or at most in a 30-minute outpatient procedure.
We dig into the engineering and biology behind both programs, potential scaling unlocks for the field, how ARIA programs drive breakthroughs, Jacques background, the role of media in shaping the future, and much more. I hope you enjoy the conversation!

AI twins won’t replace community governance — but they may help test new ways to make deliberation more legible.
An experiment with @dwddao’s Simocracy explored how AI agents could read proposals, surface priorities, and support treasury allocation discussions.

A BCI that reads the brain without penetrating it. 85 patients implanted. FDA clearance in hand. And why neural data may be the genomics revolution of our generation.
Ben Rapoport, co-founder and CSO of @PrecisionNeuro_, on the @JuanBenet Podcast.
Precision is the first invasive BCI that I could see *myself* getting, upgrading, & applying to enhancement-oriented use cases (like having my pi agent todo-list bot one thought away) without an underlying medical necessity.
Smooth, non-destructive upgrades are key! 🔑
Neuroscience is at the edge of an exponential.
Sequencing the first human genome cost millions and rewrote medicine. Once the code was readable, computer science could be applied to biology in entirely new ways.
Brain-computer interfaces are doing the same thing for the brain.
For the first time, BCIs are making brain activity readable at the spatial and temporal scales at which the brain operates, and generating data that modern machine learning can work with.

Here is Episode 2 of my new podcast dedicated to conversations on the future of neurotech, computing, intelligence, and more.
My guest Dr. Ben Rapoport is co-founder and CSO of Precision Neuroscience (@PrecisionNeuro_), Assistant Professor of Neurosurgery at the Icahn School of Medicine at Mount Sinai, and Scientific Director at Mount Sinai. Previously, he co-founded Neuralink and Simbionics (acquired by Apple).
Precision is building a minimally invasive brain-computer interface (BCI) that reads from thousands of points on the cortex without penetrating it. The Layer 7 device is implanted through a one-millimeter slit in the skull rather than the larger borehole other approaches require. It is also fully removable.
Precision seeks to help the 5 million people living with severe paralysis in the US (including 800,000 new stroke cases per year). In March 2025, Precision received FDA clearance for a temporary wired version of the system. Over 85 patients have been implanted with and used the device in clinical studies (50 at the time of our conversation). Wireless implants are planned for 2027.
We go deep on the history of Neurotech from the 1980s to the ML inflection points that triggered Neuralink's founding, why surface ECoG was a contrarian bet that's now paying off, the path to treating paralysis and stroke at scale, and why Ben believes neural data is at the same inflection point genomic data was in 2000 — a whole class of biological problems about to become tractable as computer science problems.
