Same here, I value segwit than LN but it looks like the current scalability of Bitcoin can't still handle massive transactions. I hope the Bitcoin developer will enhance the scalability capability of Bitcoin so that it can accommodate more transactions and minimize network congestion in the future.
The current attack simply shows the lack of capability of the network to handle "spiked" transaction. I hope this event will make the developer to consider and think that the current scalability of Bitcoin needs more improvement.
Scalability is more related to on-chain transactions with Bitcoin network, layer 1. Lightning Network is not and it is not on Bitcoin network.
The flow of Bitcoin development is from Segwit and Lightning Network in 2017 to Taproot upgrade in 2021. Now with Taproot we have another type of address and transactions but also have smart contract on Bitcoin blockchain.
Years ago, in the hype of DeFi 2.0 in 2020 and 2021, having smart contract on Bitcoin network sounds something very interesting and attractive but in 2023, during latest months, with Taproot smart contract holes that are exploited by Ordinals, BRC20 tokens and BSV developer team attack on it, lot of things must be upgraded for Taproot and its smart contract.
If anything should be prioritized for developments, I support on-chain things, Taproot is my favorite than Lightning Network.
