I'm 1984 the government no only controls your every move, but also you thought - through relentless propaganda and could, on top of that, read your thought - though not directly. This, in my opinion can give a government - any government - the power to control and read thought. Obviously at this time this technology is no where close to that but I feel it won't take to long to get to that point and for the government (and ad companies) to start abusing it.
TL;DR This is fine now but could be dangerous in the future

Which people getting more aware about privacy now, I think these things companies will tackle first before making it assessable to all.
