Probably the best solution to replace the inefficient method of bringing NFTs and Tokens in Bitcoin through Ordinals is an off-chain layer called Rollups, WHICH, will bring Ethereum-style smart contracts and Turing-Completeness. Whether or not Turing-complete programs are needed for Bitcoin, and by the community, is debatable. But because it's going to be built within its own off-chain network then it shouldn't truly be a problem on-chain.
It will grow to be a new trend but Ordinals will continue to stay on Bitcoin blockchain.
Because they don't need a cheaper blockchain to operate on. They need Bitcoin blockchains to make noise and attract investors to buy their tokens, NFTs. Without Bitcoin blockchain, Ordinals, BRC20 tokens and their inscriptions will have less values, smaller prices like so many available ones on altcoin blockchains.
Bitcoin developers must figure out ways to technically resolve this problem from Ordinals. They can not sit calmly and wait for Ordinals entirely to migrate to SatoshiVM, EVM rollup platforms.
