Agree that it's a timeless sound, and I think despite the critical backlash against it (just search 'dub' on the mnml ssgs twitter account) there's still a place for it, and DJs prove that out time and again when they trot out the classics (example being Optimo's recent set for boilerroom.tv - haven't heard it just yet myself but people seem to have freaked out over the fact that they dropped "Quadrant"). Dunno about Autechre, myself, only really got into one song - "Pen Expers" - but they never caught on for me, despite the fact that I've got friends who are obsessed. Seems like that might be the problem, there's only two modes for Autechre - ignorant (such as myself) or obsessed :)
Correct me if I'm wrong, but the term 'dub' was basically never used to describe BC/CR the first go-round. I always referred to it as 'minimal', as did everybody I know. I may have just been out of the loop (I'm not a DJ). But that's the funny thing about electronica. It evolves so quickly that subgenres and tags are thrown around in a flurry, and I feel like subgenres can be born and die before they even have earned the right to be referred to sometimes.
