You're right, NFT and the metaverse I guess are rudimentary concepts, but the bear market arrived sooner before they could perfect the concept. After the bear market ended, it seems that crypto's main focus will be on raising the NFT hype and metaverse again so that it becomes the perfect concept.
Both of them will not work or at least get enough support behind them. Even back when the market was in bull mode, NFTs failed to lift off and establish themselves. Metaverse on the other hand also suffers the same fate because they bring nothing to the crypto space. Even after this bear end, they might enjoy some raise thanks to market back to bull mode but I doubt they will lift off for real.
