18% of vegetative patients are actually conscious, this is pretty horrible. It's pretty much the worse possible outcome of any condition I can think of. Can't move, can't communicate, all you can do is think and watch the world go by potentially for decades while everyone thinks you're a piece of furniture. That being said "Yay!" now we can tell you're not actually a piece of furniture and we might change the channel for you once in a while.
So, mind reading seems to be the science of the year. We're seeing a lot of these type of studies, mind controlled videogames, someone just climbed a skyscraper with a mind controlled prosthetic leg etc. This is all good stuff in a general sense but it brings up some interesting moral dilemmas. How do we protect people from having their mind read against their will? Do we even need to? How would you even know you've been read? In a world where thoughts can be easily read are thoughts protected by reasonable expectation of privacy laws? As this technology advances it's reasonable to assume that remote scanning will become quite possible and probably quite easy at some point in the future.
Even worse, what happens when we figure out how to remotely alter someone's thoughts?
