The performance ceiling for non-invasive Brain-Computer Interfaces (BCIs) is rising dramatically, not from better sensors, but from advanced AI. New models can extract high-fidelity signals from noisy data collected outside the skull, potentially making surgical implants like Neuralink unnecessary for sophisticated use cases.

The next generation of AI may move beyond pure silicon. Researchers are already integrating human brain cells and "organoids" (mini 3D brains) onto chips for computation. This hybrid approach could satisfy both biological and computational theories of consciousness, accelerating its emergence.

Prasma is pioneering a new computing paradigm by using live human neurons, differentiated from stem cells, to perform computational tasks like token prediction. This "brain in a vat" approach leverages biology's inherent power efficiency and continual learning capabilities, offering a potential long-term alternative to silicon-based AI.

The next frontier of brain-computer interfaces (BCIs) moves beyond implanting electrodes. Researchers are developing interfaces where a user's own neural stem cells are grown onto a silicon chip. This biological hybrid then integrates with the brain, creating a seamless connection to cloud-based AI.

Meta's Tribe V2 is a foundation model trained on over 500 hours of fMRI data. It creates a "digital twin" of neural activity to predict brain responses to sights and sounds, raising questions about its application by a social media company.

Today's AIs are trained on the final product of human cognition (e.g., articles, code). The next great leap could come from training models on the actual neural "traces of thought," potentially via technologies like Neuralink, to solve for creativity and unverifiable domains.

Challenging Neuralink's implant-based BCI, Merge Labs is creating a new paradigm using molecules, proteins, and ultrasound. This less invasive approach aims for higher bandwidth by interfacing with millions of neurons, fundamentally rethinking how to connect brains to machines.

The next leap in biotech moves beyond applying AI to existing data. CZI pioneers a model where 'frontier biology' and 'frontier AI' are developed in tandem. Experiments are now designed specifically to generate novel data that will ground and improve future AI models, creating a virtuous feedback loop.

The current generation of LLMs is trained on the collective output of humanity (the internet). The next paradigm, according to neurosurgeon Eddie Chang, will be AI trained on individual neural activity. This will allow for hyper-personalized tools to modulate and optimize one's own brain states for specific goals.
