new in the sense that he's pushed the refinement of the technology That's what I understood as well. For example there's a mutlitude of practical problems with current in-brain electrodes, ranging from limits in the amount of them, their lifetime, lifetime of connectors, surgeries being quite difficult, possible problems with infections etc. None of them are extremely hard to solve but it basically requires a ton of money being thrown at and that seems to be Musk's plan, allowing to get like 3000 electrodes with the preamp/digitizer stage implanted subcutaneously.
