Any kind of BCI, whether invasive or non-invasive, that truly reads your thoughts, must be either open source and/or subject to government regulation, in the US. However, I do not believe that people actually will trust their government enough to just trust them on their word that a certain BCI poses no risks. I think that open source may be the only way, and from how I've seen companies talk about it, I think they also see that as their only option, at least for now. And I also think that it's both possible and likely to happen that we will have enough protective mechanisms built in to the system that we as a public won't feel much risk to using the BCI. There may be issues with first generation systems of course, but it's possible Neuralink may work out a few of those details while developing their medical units.
