This is exactly right. The only difference here is that EmDrive straight up violated a law of physics, whereas high-temp superconductivity was just a matter of degree (pun intended). I was somewhat skeptical of EmDrive, but was very hopeful about LK99. Alas, it was not to be. We'll have to take the slow road to room temperature superconductors.
