Burn rate is a measure of risk, and preemptive rounds push successful companies to raise it whether or not they need to.

Look, first of all, if a company's successful, someone will knock on your door and try and give you more money. So, like almost every round is preemptive for successful companies. And when you take that much money, $300 million, the only way to spend it is to take your burn rate up. And I always thought of burn rate as a measure of risk.
