Editor’s take

In favor

  • Modular: scales to 1,600+ channels by adding more sub-dime implants
  • FDA Breakthrough Device + IDE; first US IDE for fully-implantable speech BCI
  • Targets the specific high-value application of speech restoration

Against

  • Pre-clinical / first-in-human stage — limited published human data so far
  • Most internal hardware specs are proprietary / unverified
  • Multi-module implantation increases surgical exposure relative to a single device
