^ Have to agree with all of that.
Reminds me exactly of those things they've been selling for 20+ years with lights and sounds (can't remember for the life of me what they are called or I'd link one) that supposedly work along with your brain waves. New Age tech toys, more or less. Seems to me, all Apple did was find a way of adapting the very same technology into their products and are pretending that it's all so 'new'.
Now, there is technology that can pick up on brain waves and control stuff but it's very expensive and usually involves RFID chips and such. At this stage, usually reserved for those with severe physical disorders. Best people to research regarding that sort of technology are Drs. Michael Persinger and Jose Delgado; although, there are probably some very good new ones on the scene by now.
