The ToE sounds more and more like "V'ger" from Star Trek, The Motion Picture, forever adding disparate junk to itself, finally becoming a massive incomprehensible monstrosity.
It's not incomprehensible, it's just complex.
For example - we are now learning how navigation works in the brain. You can think about this in computer terms, to see how complex it is. You have 5 senses, and the sensors are all in different places at different angles. The idea is to reconstruct a single 3-dimensional "perception" from that, and then be able to navigate that map.
In robotics, this would involve overlaying 5 terrain maps using "best fit" anchors, and then identifying "objects" within those maps, and the being able to navigate to, from, or around those objects. The simple question of "what is an object" isn't simple at all, the separation of figure from ground requires memory.
Keep in mind, that the building blocks in the brain are very simple. A nerve cell is basically a threshold device that signals amplitude using a frequency code. Almost all of the complexity we see in the brain is due to population behavior, rather than incredibly smart neurons. So rather than reconstructing and overlaying 3-d maps, this is how the brain does it: PHASE coding. Phase coding extracts the covariances without requiring precise topographic alignment.
What happens in the information matrix (the synapses) is that covarying signals are reinforced. The covariant pathways are learned by themselves, automatically, as a result of repeated covariance of stimulus sets. The system is self organizing, it doesn't require a teacher. All it requires is a little real world experience.
The same exact method is in play in the learning of language. You've heard the expression "babies babble" - well, that occurs so the motor system can align itself with the auditory system, which is the only way the child will ever learn to create "desired" speech. In human development, object identification precedes language development, which is very logical since words describe objects.
OBJECTS are simply features that covary. The video moves together with the audio, that kind of thing.
If you'd like to know how this really works google "phase coding in the hippocampus", and if you feel like you understand it, Google on "kuramoto model".
