We haven't even begun to think about reality as it really is

Those of us interested in various cults, and "alternative" ways of trying to act and think, are always hoping to come across some new way of looking at the world.
Unfortunately, that doesn't really seem to happen. We DO get interesting new systems, which can become very complicated in their own ways though.

Just look at all the years that Scientologists have to spend on the level known as OT-7. They invest many hours every day "telepathically" contacting extraterrestrial entities that are "clinging" on to their souls. From what I've read about this matter, the procedures for removing these entities are both very "imaginative", yet it's also a highly regulated bureaucratic process.
That's a very common aspect of many religions, and also of human culture.

What I don't understand, is how the most fundamental things in our world are just about never talked about.
Like, why are we humans about as simple as we can be?
An averagely-sized mind, selected from the set of all possible minds, should basically be infinite in size. But in actuality, we're just barely smart enough to be considered fully sentient.
That's very interesting. What's more interesting is that this is somehow never mentioned anywhere.

The same thing is true in the field of physics.
Physics is both impossibly shallow, yet inhumanly deep.
Just imagine, the extrapolated implications of all the field equations essentially "prove" that the tiniest vibration in submicroscopic space creates a whole new universe (or its equivalent) just like that! (see: many worlds interpretation)

And yet, the (subjectively) absurd over-complexity of our physical universe is something that no physicist has ever mentioned, or maybe even thought about for as much as one moment, in the whole past century!
Of course, the philosophical implications of physics are not their job. But still, you would expect them to have some casual interest at least.
Mainstream philosophers should also be interested in this aspect of physics, but they're not. Now why is that?
Perhaps they just enjoy making things more complicated than they need to be?
