> Why? People don't ask hammers to do much more than bash in nails into walls.

No one is propping up a multi-billion dollar tech bubble by promising hammers that do more than bash nails. As a point of comparison that makes no sense.

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.)

That's nitpicking; in this manner you can dismiss any analogy, by finding an aspect on which it's different from the original comparandum.
