Something I was told once by a particle physicist that really resonated with me was that almost every revolution in science and engineering has a direct cause that can be traced back to finally being able to measure some new property or measure some property in an much improved way (this jives with my understanding of most things: as a random example, debugging is generally greatly improved by understanding more of the space of the problem). This seems to be one of those breakthroughs, so I'm cautiously excited. Would be interested in an expert in the field to confirm/temper my excitement.
