Give me back my brain

Today I was terrified, hearing that a machine has now been created that can turn brain waves into words - into language. Supposedly, this will create a more direct and transparent relationship between thought and its articulation. Great, now my girlfriend will know that I think her ass is fat.
On a more serious note, such a machine may be traversing not only our minds, but also a theoretical minefield, what with the predominance of linguistics-based philosophy in the last century. I would argue that thought functions in multiple discursive dimensions simultaneously, some internal, some external (social), some material even (painting?), and therefore to let it come out in a singular, linear pattern is unfathomably oppressive.
And what of thought which doesn't fit into rational, linguistic patterns, and therefore won't be able to be translated, such as unconscious thought? One might say that this does not count since the machine only works with conscious brain waves, but I resent the fact that such a system would not allow thought to slip and slide around different areas of the mind, both conscious and unconscious, in a thoroughly liberating manner.
Our brains, perhaps, are not computers, and thus should not be treated as such.
