I have to admit that I find speculation about radically advanced technology to be boring and sort of irrelevant to the myriad human issues that actually concern us here and now. But I also feel like the best science fiction is in fact about taking the here-and-now and pursuing it to a logical extreme. E.g. cyberpunk works because it's about the commodification of everything, including politics, your identity, and your body. In other words, good science fiction is like good fiction in general: it's about real social issues and real human problems.

"Fake Plastic Trees" does happen to have a 90s-style quiet-to-loud transition into a section with lots of crash cymbals and overdrive and warbly Jonny Greenwood leads. The 'Head have done mellower, including "Bulletproof", off of the same record.
