Yeah I'm not sure why this fact is buried. Yes the author is blaming cursor and railway and doesn't seem to be taking responsibility. But at the same time, many people are OK with LLMs going wild on their codebase because they know they can restore from backups. Wise idea? Probably not. But that's why they're called backups and not snapshots.
It's a mistake I'll certainly learn from. Don't believe when a cloud provider says it has backups of your shit.
