That's a nice summary. Every time I hear explanations like this about how reality is behaving, it just strikes me as so overwhelmingly obvious that this is not "really" what reality is doing. It's just a model that works, and often works quite well, amazingly. But of course, it also breaks down at some point, simply because it isn't what reality is doing. This should neither surprise nor bother us-- science was never about understanding reality completely. But a separate issue is, are we kidding ourselves that we'll ever understand the Planck domain, given the known lack of experimental probes? I would argue, certainly yes. We just have to at some point come to terms with our own limitations, and the limitations of science as a philosophical endeavor. As for building bridges and particle accelerators, it's great!
