I like that guy, I believe the 2030/2040 time was the projected "event", the 90 degree flip. I'm of the opinion catastrophes will be so rampant by 2030 they won't be able to hide it from the public.
The US military is already having to retrain pilots how to navigate via stars using the sextant, something they laughed at when I was still in the service. Don't misunderstand, they aren't at that point now where GPS is unreliable. They are however, realizing the need is going to be inevitable and waiting till the last minute to dust it off isn't a great idea.
