Ok, I have no idea about Navier-Stokes or those famous math problems which LLMs helped solve or even solved solo, but I do have a rudimentary knowledge about semiconductors and their history in particular. Even without opening the link, I can bet 1$ to anyone that they did not in fact discover anything which will result in room temperature semiconductors.

PS: edit - I was thinking about room-temperature superconductors. My mistake.
