(Have to explain the gist prior to the actual question, in shortest & simple way I could) Scientists from the university of california, in berkeley have been successful in tracing the spoken words to the pattern of electrical brain activity &, so can they see natural & eye scanned visuals on the screen. In simple words, the auditory human sense can be heard & visual senses can be extracted too, including human thoughts. That means complete mind reading is now possible with advanced computer software emulation. The idea is to measure the blood flow in the 'visual cortex', which is fed to the computer through the brain scanner. The best part is, this technology can be combined with long range scanners, which can scan a particular persons mind, whether he's on walk, bus, train or a bike. The thoughts can be read on the go, even without the person knowing it; i.e. thoughts can be eavesdropped. This can be achieved using, The MMIP technology, which is based on interactions at the subatomic level where the distinction between mind and matter disappears and effects become instantaneous over any distance(*1) A. Advantages 1. Can read minds 2. Help paralytic patients 3. Help people who cant speak 4. Can be used for military purposes & sting operations 5. Can be combined with consoles & used for mind gaming, robotics & stuff. B. Disadvantages:- 1. Breach in privacy 2. Can extract, through an individual, an important, secure & confidential information of individual, state or even a country 3. If developed or used by sinners, can be highly dangerous 4. Eavesdropping 5. No way to neutralize this technology 6. Reasearchers hack brain for pin numbers, debit cards, atm & bank accounts to uncover a security threat of this tech in an experiment(*2). The technology is new, interesting & helpful in a sense; but, its disadvantages are far more dangerous & sensitive. The references give basics while complete information is a study of various articles all around the web.
