Remember that an NFT can take many different forms: it can be an image, a GIF, a video, an in-game item or even audio. Currently, the most prominent industries in the NFT world are art and blockchain gaming — but there could be new ones, as things move fast in crypto (and perhaps even faster in the NFT world). For instance, it’s even possible to tokenize real-world assets like real estate — and why wouldn't NFTs eventually become an acceptable form of proof that you own a certain piece of land, given that it's technically impossible to forge them?
