Former Bitcoin Core developer Jeff Garzik believes in the longevity of Bitcoin but criticizes the Lightning Network, calling it a 'dead end.'
Garzik dismisses Lightning as a failure due to low usage and advocates for programmable Layer-2 solutions over payment channels for scalability.
He attributes Lightning's limited adoption to Bitcoin's 'vetocracy' governance culture and stagnant development post the 2017 block-size stalemate.
Garzik sees the future in sidechains like his project, Hemi, which integrates a fully validating BTC node in an Ethereum-compatible roll-up, emphasizing the need for programmable trust in Bitcoin's evolution.
