I saw a couple of this guys vids floating around and watched a handful, but semi-recently he made a video that went viral where he's like "I've just heard about this thing called aliasing" and I just thought "wow." I would swear I've seen this guy looking at things through scopes and also just making a lot of videos where he listens to things prior to that and I'm agog anybody took him seriously after that video.
Worse, that video has created a whole swathe of non critical listeners using scopes to find flaws in plugins. We had this in the LION thread recently. Loads of people posting scope images and/or saying even the sine wave generators alias. I (correctly to blow my trumpet for a second) pointed out that they were seeing distortion, but in the spirit of politeness i didn't point out at the time the more prescient fact that it clearly sounded like distortion if we're actually using our ears for a moment. Cue someone saying "well if you generate a saw wave at 16 kHZ you can clearly see aliasing" and OH MY GOD SAVE ME FROM THE MESS THIS VIDEO MADE PLEASE.
