Matt Angle is the CEO of Paradromics, a neurotechnology company building high data rate implantable brain-computer interfaces for people who have lost the ability to speak and move. The company's Connexus system, currently entering clinical trials, clocks an information transfer rate of over 200 bits per second (more than 20x the reported performance of comparable systems) and is designed to last more than a decade in the body.

The conversation covers the basic physics of what separates an implanted electrode array from a surface EEG, the design of the Connexus itself, and the engineering choices that distinguish Paradromics from Neuralink: hermetic sealing, modular battery placement, and a deliberate bet on durability over planned obsolescence. We also get into what it takes to manufacture a device at the micro scale, where CT scanning fit ...
