For those evenings when you start thinking about how music hasn't progressed in the last 20 years and you get an epiphany that the whole of modernity has hit a wall and isn't progressing anymore because of the limitations of our understanding of physics which is divided between general relativity and quantum mechanics and any unifying theory will make us tap into an almost unlimited energy reservoir, the ether and by our devastating human nature have the possibility of destroying the entire universe with it.
I prefer stagnation over progress...
