What changed from art to NFTs?

Art is popular because people have always been interested in rare art and antiques. In the digital age, NFTs and the NFT marketplace for digital collectibles have now replaced art and art auctions. Even though the concept of digital collectibles placed a high priority on security, there have been instances in which individuals have lost their digital collectibles due to theft. Yet, different thoughts are arising, for example, Soul Bound Tokens (SBTs), which would be safer and give NFTs a totally new look.
