The software development market is measured in tens of billions to hundreds of billions of dollars depending on which parts you're looking at so inventing a better hammer (development tool) can be expected to drive billions of dollars of value. How many billions depends on how good of a tool it turns out to be in the end. That's only counting software, it's also directly applicable to all media (image, video, audio, text) and some scientific domains (genetics, medicine, materials, etc.)
