Actually,we've had thought phones for years---they've just got some very clunky interfaces!
I usually think before I speak!
That's nothing compared to the proven technique of human body teleportation based on thought waves.
Many report that when one talks negatively about the boss to a collegue he mysteriously appears within earshot. Whereas positive conversations either do not have this effect, or do have it only if misconstrued as negative.
Proof that it was brain waves and not the voice that caused his appearance is because he could only have reached his mischievous subordinates had he started his trip while evil thoughts were being thought.
PS: The observance of this effect, ie that energy required to start this movement originates with negative rather than positive, is further proof that 'conventional current' in electrical circuits is bunk.
