A 10-second video created by digital artist Beeple recently sold for $6.6 million in an art auction. The video itself is a “non-fungible token” or NFT, a digital asset whose origin or ownership has been authenticated by blockchain technology. While this is making it easier to assign monetary values to digital art, critics like Blake Gopnik are afraid this will replicate a problem that’s been affecting the physical art sector for generations: valuing art for its authenticity but not for the art itself.
