For telepresence to work, you need to feel like your coworkers are in the same room, such that you think nothing about turning around to them and asking them a question.  Video doesn&#x27;t do this; something about the screen makes you feel like you need to present a performance, and that destroys the spontaneity that builds trust in person-to-person interactions.<p>Will a hologram do it?  I don&#x27;t know; real-time holography isn&#x27;t good enough to evaluate it.  Would VR&#x2F;AR, ocular implants, direct brain stimulation, just a giant wraparound screen, whatever?  Also don&#x27;t know.<p>I do know that given the choice between having a car drive me to work for a half hour vs. being able to conduct business with anyone in the world without leaving my house, I&#x27;d much rather have the latter.
