Ivan Sutherland predicted the Holodeck in 1965:

>Q: Can an “AI command line” replace the GUI as the primary user experience for computers, assuming the technology improves and irrespective of today’s state?

>The “related questions” have interesting slants — some of which make more or less sense.
>I think most people should be able to answer this for themselves if they look at this from a number of different angles.
>One is that we have multiple ways of “perceiving”, “knowing”, “learning”, etc. — for example by touch, sound, vision, symbolic representations, abstract languagues, etc. Besides inventing interactive computer graphics, Ivan Sutherland pointed out (in a famous 1964 paper) that “the ultimate display” should be able to do every kind of I/O that humans can do and experience. His famous last line with typical Ivan humor was “In the ultimate display, a simulated bullet would be fatal to its operator”!

The Ultimate Display -- Ivan E. Sutherland (Jan 1, 1965)

>TL;DR: The authors live in a physical world whose properties they have come to know well through long familiarity but lack corresponding familiarity with the forces on charged particles, forces in non-uniform fields, the effects of nonprojective geometric transformations, and high-inertia, low friction motion.
>Abstract: We live in a physical world whose properties we have come to know well through long familiarity. We sense an involvement with this physical world which gives us the ability to predict its properties well. For example, we can predict where objects will fall, how well-known shapes look from other angles, and how much force is required to push objects against friction. We lack corresponding familiarity with the forces on charged particles, forces in non-uniform fields, the effects of nonprojective geometric transformations, and high-inertia, low friction motion.
>A display connected to a digital computer gives us a chance to gain familiarity with concepts not realizable in the physical world. It is a looking glass into a mathematical wonderland. Computer displays today cover a variety of capabilities. Some have only the fundamental ability to plot dots. Displays being sold now generally have built in line-drawing capability. An ability to draw simple curves would be useful. Some available displays are able to plot very short line segments in arbitrary directions, to form characters or more complex curves. Each of these abilities has a history and a known utility.

>The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal. With appropriate programming such a display could literally be the Wonderland into which Alice walked.
