Another implication of this technology would be a single-stage-to-orbit aircraft that takes off & lands from a conventional airstrip. This is a jet engine that has the thrust of a scramjet, but also carries it’s own oxidizer.

Maybe. A lot depends on getting the necessary research and development done, along with detailed engineering, fabrication, and testing. Those take money and time, spurred by necessity and potential economic success.

Most of the supposed breakthroughs in technology that I have seen touted proved to be of limited effect, with many of them even being duds. The exceptions are the internet, the new genetic technologies, and the Green Revolution that averted dire predictions of worldwide famine.
