🛣️ BCIs will Run Out of Runway

“Senator Enlow: If only we could only say what benefit this thing has, but no one’s been able to do that.
Dr. Millgate: That’s because great achievement has no road map. The X-ray’s pretty good. So is penicillin. Neither were discovered with a practical objective in mind. I mean, when the electron was discovered in 1897, it was useless. And now, we have an entire world run by electronics. Haydn and Mozart never studied the classics. They couldn’t. They invented them.
Sam Seaborn: Discovery.
Dr. Millgate: What?
Sam Seaborn: That’s the thing that you were... Discovery is what. That’s what this is used for. It’s for discovery.” (West Wing)

📈 BCIs are having a moment. Billions in private capital. Headlines about paralyzed patients moving cursors & typing text. Real progress, built by talented engineers solving hard problems.

🦯 But here’s what most people don’t see.

🛫 Every one of those achievements depends on basic science discoveries made 20~30 yrs ago. Publicly funded research that characterized how neurons fire, how electrodes interact with tissue, how the brain reorganizes after injury. That knowledge is the runway. The devices are the aircraft.

🚧 Right now, we are building faster planes on a runway that nobody is extending.

🔬 I’ve spent 20 years studying what happens at the boundary between implanted devices & living brain tissue. The biology is humbling. Glial cells encapsulate electrodes. Blood vessels rupture and never fully recover. Neurons die or get displaced. The immune system mounts a chronic response that degrades signals over months~years.

🧬 These are not engineering problems. You cannot solve them with better materials or more channels or faster decoding algorithms. They are biological problems, & they require basic science to understand.

💳 Venture capital will not fund this work. There is no quarterly earnings case for astrocyte biology. No Series B for characterizing neurovascular disruption at the electrode interface. That is not a criticism of VC. It is a description of what VC is designed to do, which is build products, not generate foundational knowledge.

🏥 NIH is the only institution with both the mandate and the scale to fund this kind of research. And right now, OMB is freezing NIH funding. Paylines are compressed. Review panels increasingly penalize DISCOVERY-oriented proposals that cannot promise translational outcomes within 5 yrs. Funding delays disproportionately hit new grants.

🇨🇳 Meanwhile, other nations are investing heavily in exactly this space with explicit patience for long-term discovery. We should not assume that competitors lack the capacity for original scientific contribution. History has repeatedly punished that assumption.

🔎 Every unfunded basic science grant cycle means specific biological questions about chronic BCI failure go unanswered. Those unanswered questions become the ceiling on what the next generation of devices can achieve, regardless of how much private capital flows into engineering.

⏱️ Translation without basic science is a plane accelerating toward the end of a runway that gets shorter every year.

If we want BCIs that last a lifetime in the human brain, we need to fund the science that explains why they currently don’t.
