Earlier quoted context omitted.
Even the "neat" sci-fi ideas are often complete nonsense, such as the whole concept of sophons, which leverage a neat fringe idea of theoretical physics while running afoul of boring, well-established physics.
What's the well-established inner structure of an electron?
And then they send it off and control it remotely using quantum entanglement, except that entanglement, as far as we know, cannot be used to transmit information faster than light, let alone momentum. Furthermore, in order to be effective at anything, the sophon has to observe the world and transmit information back and forth, except that the capture and transmission of any nontrivial amount of information exceeds the mass energy of a proton by several orders of magnitude.
