MW: Did you read the article I linked for you earlier?
We have a couple of different spots that are causing our (perhaps not apparent) differences of opinion.
Clarification 1
The first is relatively simple and is partialy explained in the snopes article I linked to (which itself provides some links to additional sources). You seem to believe that humans have extraneous brain power that we can some day harness to better understand ourselves and the universe.
This is completely wrong. Some reasons:
1. Evolution would favor individuals that retained the same brain capacity without the additional costs associated with maintaing unused brain functions. The brain uses about a third of the bodies blood supply, if we only used 10% of our brain this massive diversion of resources would be 90% wasted. Any person that was able to maintain only what they used would have approximately 27% more resources to devote to hunting, gathering, procreating, or any other activity that would lead to its relative predominance versus the wasteful humans that only use 10% of our brains. It's an absolutely ludicrous argument from an evolutionary perspective.
2. PET scans (positron emission tomography) an MRI (magnetic resonance imaging) clearly show that the vast (way, way, way more than 10%) of our brain is actively used. There is no fallow portion of the brain that we may train to get in touch with our "spiritual self".
There are many other arguments that can be made, but these should suffice (I'll get more in depth if you want) to explain that the notion that we only use 10% of our brain is ludicrous. The notion that we only use 70% of our brain is equally ludicrous. We use a vast majority of our brain, there is no hidden resource of brain processing capability waiting to be tapped by sufficiently intelligent humans.

Clarification 2
You believe a soul is separate from our physical body. I respect your religious belief but understand that it is exactly that; a belief based on faith and not backed up by any scientific proof. I believe that consciousness is a property of emergence: the ability for simple rules to create complex systems. Through the interaction of millions of small simple agents extremely complex systems can emerge. A quick and technically butchered example: ant colonies find the quickest routes to food sources. Ants have an extremely small set of behaviours that they are capable of. (largely because of their extremely small brains). Ants can't go back to the colony and say "Look, there is some sugar water about 10 meters from here, go straight to the big mound, take a sharp left and it'll be on your left after you go about 6 meters". Instead they drop pheromones as they walk. Each ant is more likely to follow a path on which there are pheremones deposited than on a path in which they are not deposisted. As each ant goes down the path towards the food that path is reinforced with more pheremones causing more ants to folow that particular path. After a while all ants are following that path. Additionally the ants can not only communicate a where a food source is, but the shortest path to the food source.
Look

here,
etc. I could list a ton more examples but here's the point: an extremely simple behavior (laying a pheremone trail) can lead to extremely complex behavior (giving exact, perfectly short directions to a food source). Your brain works exactly the same way. Billions of neurons behaving in simple ways lead to very complex behaviors (memories, emotions, physical control, senses, etc.).
In my view, there is no such thing as a "soul". As a result I see the statement:
successful convergence of the body-mind-spirit.
as complete lunacy. There is no divergence between body-mind-spirit, mind and spirt are emergent properties of body.
Our difference of opinion
You believe (I'm not trying to put words in your mouth, so if I've got you wrong my apologies) that we'll become better humans and learn to use all of our powers to connect with the greater mysteries of the universe. I believe that we will understand the greater mysteries of the universe but it will be through the merging of technology and our bodies.
We're not going to get more brainpower through evolution. Brain power and reproductive success are not covarient (they don't increase together). In fact education tends to be highly
negatively correlated with reproductive success. If anything, from an evolutionary perspective, human mental accuity (on average) should be decreasing.
What I think will happen, that I think is inevitable, is that we will become cyborgs. It sounds scary and sci-fi but it's already happening. People have artificial hearts, knees, etc. Artificially enchanced brain function will be yet another threshold that we eventually cross. It will probably start with something innocuous and not very controversial, repairing brains damaged by alzheimer's, for example. People will quickly realize, however, that no matter what your religion taught you the human body is far from perfect and has much room for improvement, including in mental areas. A quick example: why does it take you so long to drop a hot pan? Even with the body cheating and only sending the signal back to your spinal cord (instead of all the way to your brain for processing), it still takes a finite amount of time for the electrical signal to be passed along the nervous system. The speed at which this signal is passed is so vastly inferior to computer systems it's not even comparable (meters a minute versus hundreds of thousands of kilometers a second). So we'll definately speed up the connections between neurons.
Secondly your brain can only contain so many memories. We only have so large of a working memory. Eventually we'll have links between our brain and vastly more powerful computers that allow us to extend these capabilites.
So what I'm saying is that no spirtual-mental-body link is going to make us smarter. In fact, I don't think that there is such a thing. Still, it is absolutely unavoidable that humans will merge with our own technological creation to vastly increase our mental acuity.
Sorry for the long response.
Cheers,
