Telepathy will be real once we master brain computer interface

I already communicate without speech, I'm doing it right now to someone I've never met and don't know the identity of, who is receiving only the thoughts I wish to share. Why would I go beyond that?

Besides, I can also share thoughts with those I do know without speech. I text my wife when I don't want the kids to hear our joke, I can even include pictures to get the message across if I don't have the words.
