Oh, but there's new libraries out there: less in the physics (which remain as fundamental as the unchanging principles of computer science and mathematics) and more in the applications. For instance, right now I type this I am sitting in what is, last I checked, the tallest modular building in the world: parts assembled at factory offsite, and trucked in by crane. In other construction techniques, we can see things like 3-D printing, in variants that range from "extruding concrete in boring square shapes on the foundation" to "laser-sintering alloys into exciting new organic designs".

There are exciting new materials, as well; would you consider building with cross-laminated timber? Would you build a plane with carbon fiber? Okay, how about one with a maneuvering characteristics augmentation system?

(POSTSCRIPT: Just checked, not the tallest anymore.)
