I believe that sometime in the future, perhaps within the next 5-10 years, Bitcoin's role will begin to shift from being merely a speculative instrument to becoming a decentralized financial infrastructure.
Bitcoin can be used by anyone from individuals to companies and governments. It's only if they are interested in and have deep knowledge to see great things they can get with Bitcoin blockchain and Bitcoin transactions. While Bitcoin can provide many great things, it is different than it will become a financial infrastructure and replace governmental, central bank systems in any nations or globally.
At the protocol level, this efficiency will increase through the adoption of taproot and layer-2 optimizations, perhaps like the Lightning Network, which will open up opportunities for low-cost, real-time transactions and potentially global scale. Modern integrated payments, open APIs, and user-friendly non-custodial wallets will make Bitcoin more compatible with the needs of the digital economy.
Bitcoin will have more developments technically and it will expand its adoption more but cheap transaction fees is not main reason to make Bitcoin becoming more popular since 2009. There are altcoins with cheaper transaction fees but people dislike altcoins and choose Bitcoin with solid reasons to do this.

And network resilience is supported by node decentralization, increasing hash rates, and flexible market-based transaction fees.
Bitcoin is not altcoin and token so it has no interest with tokenization progress.
Bitcoin is not fiat currency and it has no interest with development, test and launch of CBDCs.
