Engineers have pretty completely exploited the big basic physics discoveries of the 19th and early 20th century.
Then next great wave of change will come from the life sciences and materials science. Engineered life forms and materials with near magical properties.
Physics, not so much. What can future technologists do with the “multiverse”?
They just figured out how to cram a LOT more data thru a narrow radio band ("unlimited bandwidth" may overstate, but not by much). Quantum computing is gathering speed. Entangled particles exhibit instant communication at significant distances. Teleportation & cloaking is achieved at increasingly larger scales.
Oh, physics has plenty to deliver on in my lifetime.
