Way Station was written in 1963. At one point in the novel, the author describes a mixed reality experience that the protagonist, Enoch has. The description by Enoch at the end of that session is how some feel today after a good VR experience. For many people, the Holodeck from Star Trek: The Next Generation (1987 – 1994) may have been their first encounter with such technology as described in Way Station. Clifford Simak was definitely ahead of the curve, it’s no surprise that many technologists and researchers gain inspiration from science fiction writers.
