Both are similar tech as in they are brain interfaces but Synchron's approach is considered 'minimally invasive' as it is an endovascular approach, whereas Neuralink is consider majorly invasive.
I really think that implantables are the answer but most doctors would disagree.
Well, everyone thought Apple was crazy introducing iPhone in 2007, that was easily breakable, needed charging overnight and why the hell would we use such a small screen to interact with the Internet.
I guess some people like Jobs and Musk can see the future better than others but the problem here is the goddamned archaic FDA and similar regulators.
I think they are going to put an obstacle after obstacle in Neuralink's path. Maybe for good intentions, but also maybe delaying treatment that is badly needed by many millions.
