I'm not sure what timescale Elon thinks this company is on, but even that first point is probably much further away than any new product team at Google could survive for (and no this is not a "Google is ADHD" joke, although that is also kinda true). Additionally, an implant is pretty damn invasive. So some cute demos or niche consumer applications are not going to cut it. IMO the two possible paths here are either this will be an R&D money sink for our entire lifetimes (maybe funded by Elon for fun, maybe some government grants, etc.) or they will primarily operate as a medical device company. The implants they are developing are definitely a tech improvement, so they could realistically improve existing DBS treatments. The company could also work on their own novel DBS paradigms for treatment of specific diseases. A lot of DBS (especially for psychiatric diseases like OCD) is currently rudimentary AND we have a poor understanding of why it even sort of works. But it does clearly work for at least some subset of patients, so there are real avenues for continued development.
