Nice article, but it's more like reading stimulus reaction while reconstructing it in a form that's similar to the original. But it has flaws. Based on the recordings you can make out pretty much any existant song (or memorized recording) but not original thoughts. Everyone can remember the beats of a song, but also everyone makes word associations in different ways, depending on which concepts sticks.
Very cool for an interface tho. It would be possible to use it as base for composers, if it's possible to interpret original hummings, or beats (what would I know, I'm not a musician), which would require training.
But there is a catch
Continuing to probe musical perception is likely to be difficult because the brain areas that process it are hard to access without invasive methods.
nothing gets out on its own
This is what I mean by your logic. Do you understand the difference between fiction and reality?
Because surveillance never has been an issue /s. Did you just read the last comment and ignore the rest? One is a real problem, the other is fiction. Do you understand the difference?
Sure man, let's make a law about something we know nothing about, what could go wrong.
