Nothing's busted, Dave is rushing to judgement (disclaimer: I'm going by the title, haven't watched the vid. EEVblog's usually on the money though. See eg. his vids on solar roadways / bicycle lanes. That just racked up another "confirmed, it's a bust" over in the NL).
In this case: too early to tell. The jury is still out.
From what I've read, doesn't look good though.
The title is a bit clickbaitey but I didn't want to editorialize it. Dave recreates the video demo accompanying the recently announced LK99 superconductor using a (non superconducting) copper clad PCB and HDD magnet.
I watched the video and I agree. He goes a bit sensationalistic and makes fun of the researchers for that specific video, while still saving face saying they could still be on to something.
