There does seem to be a certain amount of failure that is necessary to be able to get it right. One would expect that number to decrease over time with each new rocket company but I don’t believe it decreases as much as each company would like to believe.

Move fast and blow things up early rather than slowly. The minimum number of explosions must be met!
