I will give you one thing. We iterate faster. We can try a dozen number of approaches in a week and often we get immediate feedback on what works and what doesn't work. I hardly doubt any other kind of engineer has tried as many things as any of us do. We build, and build and build. We don't spend a lot of time building one thing. Or if we build one thing it is made of many things that we build, rebuild, refactor and replace over and over.
