I don't know that any similar reasons have been named here. > There is no evidence at this point in time that we know all there is to be known at the next level energetic collisions. The whole idea that we are at the end of the line for particle accelerators smacks of huge hubris: we know all there is to be known. This is a massive strawman argument to use, especially against someone like Dr. Hossenfelder who is a working physicist.
