Will any of the original 7 LK-99 researchers excluding w&m prof speak at int'l conf (not APL) by end 2030?

New, stricter criteria:

Any of the 7 people listed here or in earlier versions as the original 7 researchers excluding Hyun-tak Kim. https://en.wikipedia.org/wiki/LK-99 will speak at a conference as described below, excluding ones run by APL (which is some sort of "easy-to-get-into" conference/journal thing which apparently does low/no quality filtering)

The must be about physics. It cannot be an apology or examination of past failures; they must be presenting their own new research (new to the world, including lk-99) positively, and have been selected due to the merit of the research, not as an example of failure or other similar fallout from LK-99's failure. Obviously, if LK-99 turns out to be true, then speaking out about it will be frequent and common, and this will YES easily. It can't be just a poster they have to speak.

The conference must be attended by at least 100 researchers in the field of physics, and must be about physics. It should be a "mainstream" conference. Hard to define, but basically, one which say at least 20% of active physics professors do not dismiss as pseudoscience. "International" means at least some speakers must be affiliated with overseas universities or research labs, etc. bit including the LK99 guys.

There has to be evidence such as photos of the speech, a video or a recording. Or written support from multiple, real, independent, currently employed "legitimate" physicists.

Judgement will be about whether any of them has actually been approved by a real physics group to speak.

EDIT 2/23 The conference must be "selective", that is, it must not be one where you 1) have the credential 2) join some org 3) meet a low bar.

It should be more like one where there is a review process which does not accept all or even most of the potential speakers; instead, it looks for the best people to speak.

@Ernie Sukbae Lee will speak at The 9th Asian Conference on Crystal Growth and Crystal Technology(CGCT-9), held at Jeju, South Korea in June.

It is easy to verify from the list of invited speakers that the conference is international. As far as I can tell, the conference is of good reputation. According to Journal of Crystal Growth, CGCT-7 was attended by more than 400 researchers, and there is no reason to think it would be smaller this time. CGCT-8 was held online due to the pandemic.

I couldn't get information about selectivity of CGCT, but in general "invited speakers" is selective, unlike APS March Meeting. I would like to get a preliminary clarification whether CGCT talk would resolve this YES.
