EEVblog's input on this is actually hilarious, if you haven't seen: https://www.youtube.com/watch?v=QHPFphlzwdQ

Being loud and obnoxious is at best orthogonal to being correct. I'm not on either side on the LK99 question)
Having skipped to his analysis of the video, I find him pretty convincing.

He explains why the video is bunk using information provided by the lab, and basic physics. And then 'replicates' using his own sheet of metal and a magnet.

Also, he raises the fact that it's a commercial lab.

I've downgraded my level expectations a couple of orders of magnitude. But hey, let's hope for a miracle.

Just watching it. He brought up something I noticed also, showing the magnet moving the hanging copper plate with the material deposited on it... In like basic physics class you go over eddy currents induced by moving magnets, isn't that all we see there? I can't understand how this showed anything other than that?

Thunderfoot comment though seems ridiculous. It would be irrelevant because it is a ceramic??? lol. They proposed a mechanism how it works! Obviously this would just be the first step. That's like saying the first transistor was irrelevant because we don't use that design anymore.

I liked his actual point, too! But it's being devalued by his demeanor
It shouldn't devalue the point. As you said, it's orthogonal.

What part of the video I linked to was "loud" or "obnoxious"? I am not sure if you even watched the video...
Are you Australian by chance?

He's really laying on the sarcasm during the intro, I could totally see that getting misconstrued by someone not familiar with our flavour of sarcasm.

Despite not being of Australian origin, I can understand how one could interpret his initial remarks as being tinged with sarcasm. In my personal analysis, however, I found his comments to be injected with a considerable amount of wit and humor.
as a non-australian but native English speaker, I found the video annoying because it's padded and the jokes/sarcasm weren't really all that funny. If you trim out his YouTube-OverReactions, I think the video goes down to like 1.5 minutes in my mind and still conveys the same information, perhaps even better.

I get probably this is a popular video maker in whatever sphere he's in, but as an outsider, it's difficult to get into the video because of what I attribute as the presenter's YouTube personality.

(also it very much so bugs me to see people using Chrome and see all the nags for notifications, the random extensions/features, etc. And any browser without uBlock origin throws me as it takes me a minute to realize why all the websites look so bad, but that's just a personal issue :) )

I've been wondering what the "hanging copper plate" demonstration would look like if you were just seeing eddy currents. I kind of assumed you wouldn't see much movement because otherwise that makes the whole demonstration seem dumb.

...and based on that demo, it really does seem like a dumb way to demonstrate your miracle material. Really doesn't inspire confidence.

I find it very disappointing if not worrying that this wasn't picked up by more people... This is something any of us could have noticed.
Most people haven't seen that video. Most people have only seen the levitation video.
Good points made, but the attitude is absolutely repulsive.
