AI labs as future biotech companies: the race to read and write the brain
Andrew Huberman opens with a prediction that major AI labs won’t remain “LLM companies” in the long run. He argues their underlying ambition centers on neuroscience—specifically, non-invasive ways to read from and write to the human brain.
- •A prediction that major AI labs will become biotech companies focused on the brain
- •The stated long-term goal: non-invasive brain read/write capability
- •The claim that AI leaders understand more neuroscience than people assume
- 0:41 – 6:24
Energy as the bottleneck for top performers: sleep needs, self-assessment, and redlining
Patrick O’Shaughnessy frames an emerging bottleneck: elite builders may be limited less by opportunity and more by sustained energy. Huberman responds by emphasizing individual sleep requirements, the reality of rare low-sleep outliers, and the importance of knowing when high performance becomes harmful “redlining.”
- •The idea that modern ambition and opportunity make energy a limiting factor for high performers
- •A caution against copying extreme sleep patterns based on famous outliers
- •The importance of honest self-assessment about sleep needs across life stages
- •A distinction between having high output and being in an unhealthy internal state
- •Early-career intensity versus later shifts toward recovery and sustainable performance
- 6:24 – 7:16
The overlooked superpower: downshifting fast and falling asleep on demand
Huberman identifies rapid cognitive downshifting as a rarely discussed determinant of long-term performance. Patrick shares his own difficulty transitioning from an exciting day to sleep, setting up a deeper discussion of what sleep onset requires physiologically.
- •The ability to “switch off” as a hidden driver of recovery and longevity in performance
- •Patrick describes taking hours to fall asleep due to a racing mind
- •Huberman frames sleep onset as trainable rather than purely luck or temperament
- 7:16 – 10:48
A neuroscience framework for falling asleep: thoughts, heart rate, and proprioception
Huberman lays out three prerequisites for sleep: quieting thought, slowing heart rate, and reducing awareness of limb position. He explains how shifting attention to pure sensation and emphasizing long exhales can reduce arousal and help initiate sleep.
- •Three requirements for sleep onset: reduce thoughts, slow heart rate, and diminish proprioception
- •Turning off thoughts as a skill built by moving attention from planning to sensation
- •Long exhales as a tool to slow heart rate via respiratory-linked mechanisms
- •A distinction between this sensory-attention approach and traditional meditation as he describes it
- 10:48 – 14:19
Rocking beds, eye-movement hacks, and sleep tech that drives REM
Huberman describes evidence that rhythmic rocking can accelerate sleep, even in adults, and connects it to eye movements and balance circuitry. He then discusses an emerging eye-mask technology that induces patterned eye movements to help people fall asleep faster and potentially increase REM sleep.
- •Rocking at specific rhythms can help adults fall asleep faster in studies
- •A proposed mechanism involving compensatory eye movements and balance/proprioception pathways
- •A do-it-yourself approach: moving eyes under closed lids in different directions to “confuse” the system
- •An eye-mask technology that measures REM and uses stimulation behind the ears to induce eye movements
- •A claim that such devices may be close to commercial release and could meaningfully alter sleep architecture
- 14:19 – 19:48
From sleep tracking to state control: non-invasive devices to shift focus and calm
Huberman broadens from sleep tools to a near-future where devices modulate brain and body state in waking life. He argues we currently rely on blunt levers like temperature, breathing, caffeine, and cold exposure, but expects increasingly direct non-invasive stimulation to tune focus and relaxation.
- •A projection that brain-state shifting will move from deliberate habits to device-driven modulation
- •Sleep as the first domain where people accept measurement and intervention
- •Breathing practices summarized as inhale-emphasized versus exhale-emphasized for alertness vs calm
- •A vision of eyeglasses or similar wearables that adjust autonomic state throughout the day
- •The idea of better recovery and performance via more precise timing of activation and rest
- 19:48 – 23:51
What’s gone wrong in health optimization: theatrics, low standards, and a coming reset
Asked about the biggest challenge in his field, Huberman criticizes the public discourse around health and longevity as driven by attention and performance rather than rigor. He predicts a downturn in “optimization” culture followed by an influx of more serious, well-trained educators.
- •A claim that health and longevity discourse has become dominated by theatrics and low barriers to entry
- •A contrast between gaining attention and sustaining respect
- •A discussion of extreme “optimization” content and the public’s growing fatigue
- •A prediction of a downturn followed by the rise of more trained PhDs/MDs in public education
- •An expressed desire for more serious peers and higher-quality discourse
- 23:51 – 27:56
The central research frontier: non-invasive brain writing with spatial and temporal precision
Huberman calls the biggest and most exciting research challenge the ability to non-invasively write to the nervous system in sleep and waking states. He discusses invasive neurosurgical work as proof of what’s possible, then emphasizes the push toward selective, precise modulation without breaching the skull.
- •Non-invasive activation or quieting of brain regions as the major frontier
- •Why breaching the skull is a major barrier outside of clinical necessity
- •A focus on spatial and temporal precision, plus graded (not just on/off) control
- •Examples of high-impact goals such as restoring speech or walking in severe impairment
- •The argument that AI companies’ real “arms race” centers on brain-state modulation and control
- 27:56 – 30:45
How we read and write the brain today: electrodes, EEG/fMRI, ultrasound, TMS, and drugs
Patrick asks what “reading” even means, prompting Huberman to outline methods across invasiveness and fidelity. Huberman contrasts direct recordings with broad measures like EEG and fMRI, then explains how pharmacology already ‘writes’ to the brain by shifting activation thresholds—though bluntly and system-wide.
- •Neural signaling described in terms of action potentials, thresholds, and graded dynamics
- •Reading methods ranging from invasive recordings to EEG and fMRI
- •Stimulation approaches mentioned including ultrasound and transcranial magnetic stimulation
- •Pharmacology as indirect ‘writing’ that raises or lowers activation thresholds
- •The core challenge reframed as willingness to accept invasiveness versus desired precision
- 30:45 – 33:49
Implantable devices and near-term adoption: vagus stimulation and under-the-skin tech
Huberman argues that the next wave may be implantable devices—less invasive than brain surgery but more direct than wearables. He discusses vagus nerve stimulation, its effects on alertness and depression treatment, and suggests entrepreneurs may increasingly accept small under-the-skin implants.
- •Vagus nerve stimulation described as more complex than “calming,” with many excitatory pathways
- •An example of real-time mood shift during vagus stimulation as Huberman recounts from a colleague’s work
- •The question of consumer willingness to go ‘under the skin’ for stimulation devices
- •A story of a Neuralink neurosurgeon using an under-skin device in the hand for door access
- •A prediction that implantable devices will matter more than trends like peptides in the near future
- 33:49 – 37:10
Do we understand the brain well enough? Where models break down: memory and thought
Patrick presses on whether we have adequate models of brain function to safely intervene. Huberman argues we understand sensory systems and many deep-brain drives relatively well, but describes memory and thought as areas where foundational assumptions may be shakier than textbooks suggest.
- •Confidence in understanding at the sensory periphery and certain deep-brain ‘switches’
- •A discussion of appetite-related circuits and how certain drugs act on hunger circuitry
- •Prefrontal cortex framed as important for strategy, context, and impulse suppression
- •Memory and thought highlighted as the murkiest domains for a clean brain model
- •Concern that intervention could have unintended consequences because neurons are reused across functions
- 37:10 – 46:23
A disturbing memory finding: sequence may not matter—and why that complicates neurotech
Huberman recounts experiments in which neurons tagged during learning produce the same behavioral output even when reactivated in different sequences. He explains why this challenges a common view that precise firing order is essential, raising both opportunity and risk for future read/write technologies.
- •A description of experiments tagging neurons involved in learned behaviors and reactivating them later
- •The surprising claim that reversing sequence or activating neurons simultaneously can still yield the same behavior
- •Why this challenges textbook assumptions about temporal order in memory circuits
- •A tradeoff: potentially easier ‘writing’ versus greater risk due to neurons’ multi-purpose roles
- •A warning that we still lack a clear account of what thoughts are, complicating safe stimulation
- 46:23 – 50:38
The cyborg line: direct autonomic readouts, privacy concerns, and ‘benevolence’ safeguards
Patrick raises fears about identity and control if technology can manipulate brain states. Huberman argues people will gradually accept direct nervous-system measurement, cites a device concept that reads autonomic activity more directly, and insists future stimulation must include safeguards and user control.
- •A concern about being ‘played like a piano’ and losing agency
- •A prediction that direct nervous-system measurement in waking states is the next hurdle for public comfort
- •A described tool that measures autonomic activity and distinguishes distress from high-arousal states
- •The idea that better feedback could reveal unseen stressors and stress ‘tails’ after events
- •A recurring emphasis on safeguards, control, and design constraints for stimulation devices
- 50:38 – 1:13:26
Genetic engineering becomes part of the control stack: opt-in vulnerability and CRISPR implications
Huberman sketches a future where targeted genetic modifications enable selective stimulation—potentially via light or ultrasound—without needing implanted brain electrodes. He then discusses the controversial CRISPR editing of twins to remove an HIV receptor and the speculation about cognitive side effects, using it as an example of how fast the world may move.
- •A scenario where viral vectors introduce neural ‘tags’ enabling selective external stimulation
- •The idea of multi-factor safeguards (e.g., an ‘AND gate’) to prevent uncontrolled activation
- •A comparison between engineered brain modulation and existing self-administered stimulants like caffeine
- •A recounting of a scientist who announced CRISPR edits in twin babies to delete an HIV receptor
- •Speculation discussed about possible memory/cognition implications and the broader trajectory of human genetic selection
- 1:13:26 – 1:19:34
Meaningful success and the closing lesson: matching work to genuine curiosity
In the closing question, Huberman shares a formative moment in graduate school when a future advisor urged him to follow the questions he cared about most. He connects that guidance to long-term success and warns that pursuing “success” while ignoring genuine curiosity leads to a slow erosion of meaning.
- •A story about leaving one lab to join Barbara Chapman’s lab based on true interest
- •The idea that success depends on how well work matches genuine curiosity
- •A reflection on how that choice shaped his publishing output and career trajectory
- •A broader argument that ignoring curiosity to chase external definitions of success is tragic
- •A final framing that authenticity in direction—not just outcomes—is central to a sustainable arc
