The Hidden Cost of 'Move Fast and Break Things'
Facebook's famous motto became Silicon Valley gospel: 'Move fast and break things.' It captured something real about startup culture—the importance of speed, iteration, and being comfortable with imperfection. But fifteen years later, it's worth asking: what exactly did we break?
The answer, I've come to believe, is more than we realized. We broke trust. We broke privacy norms. We broke the attention spans of billions. And in many cases, we broke the companies themselves—building on foundations so shaky that no amount of engineering could stabilize them.
The Speed Trap
Speed creates its own reality distortion field. When everyone is moving fast, slowness feels like falling behind. What gets lost is the distinction between two very different kinds of speed: speed of execution and speed of decision-making.
Move fast on execution. Move slow on strategy. Most companies get this exactly backwards—they're slow to ship but fast to pivot.
The companies I've seen succeed weren't the ones that moved fastest. They were the ones that knew when to accelerate and when to pause. They had conviction about their direction, even as they iterated rapidly on the details.
What 'Breaking Things' Actually Means
In the original context, 'break things' meant being willing to ship imperfect code, to test in production, to accept that some features would fail. This was genuinely liberating for engineering culture. It gave permission to experiment.
But the philosophy metastasized. 'Break things' became justification for shipping products without considering consequences. For disrupting industries without understanding them. For treating regulations as obstacles rather than evolved wisdom.
- Uber broke taxi regulations—and in many cities, broke the livelihoods of drivers
- Social media broke information gatekeepers—and broke our epistemic commons
- Crypto broke financial regulations—and broke the savings of countless retail investors
- AI is breaking content creation—consequences still unfolding
The Debt Comes Due
Technical debt is a well-understood concept. You take shortcuts to ship faster, knowing you'll pay it back later. What we're less good at acknowledging is organizational debt, cultural debt, and societal debt.
Organizational Debt
Companies that move fast accumulate organizational debt: unclear responsibilities, undocumented processes, institutional knowledge locked in a few heads. When those people leave—and they always do—the debt compounds rapidly.
Cultural Debt
Speed culture creates its own norms: heroics over sustainability, shipping over polish, growth over profitability. These norms attract certain people and repel others. Over time, the culture becomes self-reinforcing—and self-limiting.
A Different Model
The alternative isn't moving slow. It's moving intentionally. It's understanding that some things are worth breaking and some aren't. It's building systems that can absorb failure without catastrophe.
The most impressive companies I know aren't the fastest. They're the most deliberate. They ship quickly but think slowly. They experiment constantly but commit carefully. They understand that sustainable speed comes from foundations, not just velocity.
The goal isn't to move fast. The goal is to win. Sometimes those are the same thing. Often they're not.
What I'd Tell My Younger Self
If I could go back to when I first started building companies, here's what I'd say: Speed is a tactic, not a strategy. Know what you're optimizing for. Understand what you're willing to break—and what you're not. And remember that the things you break have a tendency to stay broken.
Move fast, yes. But think about what you're breaking. Some things are worth breaking. Some things aren't. Wisdom is knowing the difference.
