I am quite optimistic about these kinds of technologies, and I can see their potential.
However, I cannot trust a billionaire with that. I don't want ads in my brain. If it is open source and tested, I can give it a second thought.
there's this really small side note in the Neil Stephenson near future book The Diamond Age where most of the people that decide to get first gen neural interfaces get infected with spam bots and get constant popups ads that quickly drives them all insane and that has always really stuck with me and there is no way in hell I'd ever get an implanted neural interface.
A side note to the side note: Why tf there are no series/movies/games based on Neal Stephenson's books?
Not to mention go septic and 💀 from real life infections. Being inundated with spam ads with a splitting headache and a fever sounds like a special kind of hell.
