He told me this idea in person, and it was speculative in nature.
It’s related to his observation that no one had become genuinely enlightened since he had become free - the last person he considers ‘genuinely enlightened’ was Franklin Jones aka Da Free John aka Adi Da (funny story - my uncle is a follower of his and would sometimes send my mother his books). Every other person who claims to be enlightened has either been a faker or what Richard calls of the ‘just add water and stir variety.’ I’d be interested if anyone here has any insight into precisely what he means here.
In any case, his explanation for why none have become enlightened since Actual Freedom first became possible was that the psychic web has become weakened in some way which no longer allows enough requisite energy for enlightenment to occur. He likens it to a hot air balloon which has been punctured, not allowing enough hot air to gather for the balloon to rise into the air.
Similarly, as more and more people become free, it may be that becoming free takes less and less ‘doing,’ and at some point perhaps the psychic web will no longer be able to even support normal reality.
And, even more intriguingly, people may not notice that anything had happened: Richard recounted a story to me of a woman he met who entered a PCE without really knowing what it was or noticing much of a difference - she was essentially like “oh, everything has always been perfect!” and then exited it after a week or so, again without ever noticing that anything strange had happened.

Speaking to the larger topic, my biggest eyebrow-raising moment on the AFT came with reading this, a part of the description of Vineeto becoming fully-free:
…those potent surges were of such a magnitude that a rather remarkable man on another continent experienced what he had earlier reported as being a ‘gentle energy’ (which he had further described, then, as being ‘totally harmless’) pouring into him, transfixing him in a sort of immobility (not of the body) and overwhelming him to such an extent that he communicated with me four days later, via email, and we were able to establish, with all due care taken in respect to time-zone differences, that the two events were congruent.
Strange happenings, and yet, apparently, occurring entirely in the actual.
Personally, I am satisfied by the description that this universe is both infinitely large and infinitely dense; there is always more to see, and more to learn - and far, far more than I will ever personally know or experience. There is some explanation that brings all this to square, but it is ‘above my pay-grade’ as well as beyond the view of our physicists and scientists.
Mostly it’s him pottering around, making fun of hippies … much like my life now 
but I think once again this really is all about confirming this experientially for yourself as opposed to trying to deduct it on a purely intellectual level.
