The answer to the question of whether or not a 15s block time could be smoother is that it is possible, but it won't happen overnight. Block time is a measure of the time it takes for a new block to be added to a blockchain, and it is an important factor in the overall performance of a blockchain. As the blockchain network grows, the block time can become slower as more transactions are processed. To make the block time smoother, developers need to optimize the code and algorithms that run the blockchain. This can be done by improving the scalability of the network, reducing the complexity of the code, and improving the efficiency of the consensus algorithm. These improvements can take time, and it may take several iterations before the block time is as smooth as possible. But with the right strategies and investments in development, it can be done.
