Ok, sorry, misunderstood you. Specifically on this subject, we only spoke about it a day or two before the OP, then I found that goofy Russian's WSJ article. I guess we only spoke about it then, and only in that I found it highly interesting and unusual that a scientist, even if I am using that title broadly, came to nearly identical conclusions to the far-out crowd.
I have discussed Earth changes with mum for many years, and there are many maps to look at that show a dissolving US - google "Earth change map", there is abundance. Those maps were to be caused by natural phenomena alone, like quakes and volcanoes, yet are not wholly dissimilar to the maps that came out in the recent discussion.
