BERLIN — As virtual reality breaks into the art world at all levels, a host of questions about curation, conservation and commercial value is still being explored.

The Berlin-based artist Olafur Eliasson said that we were only in “the Stone Age” or prehistoric period for the medium.

“There is a new space out there where a lot more people will have access to artistic experience,” he said last week in a panel discussion here at the Art Leaders Network hosted by The New York Times. He added that “the quality of the glasses is getting so much intensely better” over the three years he has been experimenting with virtual reality.

The technology is far from ubiquitous, but companies such as Samsung, Google and Microsoft are invested in its future, and some recent studies forecast rapid growth for virtual- and augmented-reality headsets in the years ahead.
