What does anybody predict will be the future of this octave of densities?

That's an interesting  question because it seems like it could tip either way.  On one hand,  the proliferation of abstracted speech and electric gizmos create a multitude of ways for people to "tune out"  the universal truths in favor of (largely self-oriented) experiences based solely upon distortions.   Based on this,  I would say the tendency would be towards a thicker veil.

HOWEVER,  God is in all things and Truth is in all things,  and so the proliferation of all those clever/unique interactions also open the door for entirely new ways to find and connect with the Creator.   The Internet,  especially,  has made it possible for people to explore the world and its ideas in ways that simply were not possible prior to the 21st Century.   Someone with a smartphone could just as easily spend their time researching philosophy or attempting to better-understand humanity as a whole... Or they could spend their life playing Facebook games.

So the more ways we find to thicken the veil would also,  simultaneously,  open up many new windows into the veil,  for those with the eyes to see it.  It still boils down to a matter of free will and what an individual is searching for on their own life path.

Interesting ideas. My only critique of what you're saying is that it seems like you are referring to a 3rd density planet like ours that is so close to 4th density as to actually be 4th density (Q'uo, in fact, says that we are now in 4th density; the harvest, according to Q'uo, was in 1987). So, it seems that you are describing a 3rd density situation that is on the cusp of 4th density (as far as the technological progress that you are describing, goes). A true 3rd density would be more like any time period (here on 3rd density Earth) before now.

That era of 3rd density is what I am primarily referring to as being thicker.
