I just watched the whole thing. It was definitely worth it, nice discussion. They brought up some valid points and highlighted the importance of certain aspects of recording quality, but it's important to have in mind that there are a million other things you have to take into consideration. Recording and mixing in 192khz/32 might sound good but it will punish your pc/mac. Preserving the full dynamic range of a song may result in a more natural listening experience but chances are the song will be ignored because it's not loud enough to grab the listener's attention. Using a minimalistic setup will result in a real sounding mix but it will also limit your creative possibilities and so on...
