That's because "go fast and break things" was a stupid plan for children and criminals. It worked sometimes in the same way that some people who move to LA to become A-list actors succeed, but that doesn't make it a good plan. Slow IS faster. But slow can also be slow; you can go slow because you're doing it right, or you can go slow because you're dragging cinderblocks behind you for no reason. The trick is telling those two things apart.
