They used four fixed electrode arrays, like pushing a miniature bed of nails into your brain, which is far more invasive and less advanced than Neuralink's one device with threads individually implanted by robot. Neuralink is not exclusively for speech, focusing more on general computer use. This is mostly about where the device is implanted, not the device's capabilities.
As for FSD, it leads by far for systems you can own, and while it is not as good as Waymo it is much cheaper and still rapidly improving. It is too early to say which approach will ultimately win.
