I respectfully disagree with the major premise of your post. In every decent hacker there is a bit of masochist. Toolchain development is always the least glamorous role in the company and one of the most important. In the game industry you can usually tell the difference between successful studios and finger crossers by examining their toolchains. I'm not saying that "this" is the big step forward, but any technology that maps more directly to our mental model or increases the pool of competent people that can interact in it advances the science of computation. If i were to point to a specific example I'd say Kismet in the Unreal Engine is the best real world implementation I've seen. It redrew the line between artist and technical artist.
