We don't need Lightning Network at the current situation,because the bitcoin transactions are already fast and cheap.LN will work only when the blockchain is stuck and the transactions become expensive and slow.
quite the opposite.
a second layer is only working if the first (underlying) layer is working fine. Lightning Network needs bitcoin to work fine meaning to have reasonable on-chain fees and little to no backlog. otherwise if there is a huge backlog like during the 2017 spam attack and fees are huge then you can not use LN either.
still nidacoinlove is talking nonsense though. nothing has failed! he seems to be caught up into some altcoin bag holding scenario.
