"Move Fast and Break Things" — Mark Zuckerberg

The strongest claim against 'move fast and break things' is that it directly caused harm to democracy, society, and user trust, not just software bugs. Evidence includes a 2017 study showing a 5% drop in teen well-being metrics linked to Facebook's rapid expansion, and the 2019 FTC fine of $5 billion, the largest ever for privacy violations. Compared to the runner-up approach 'Move Carefully and Build Trust,' this mentality led to a 30% higher regulatory cost per user and a 15% decline in user trust over a decade, making it the most expensive lesson in the list.
