I think your falling into a bias of too closely correlating the pattern a cortical column recognises as to what it means in relation to the whole process. Separate columns can be programmed and used in isolation to play games and recognise patterns we know and can associate with, but you need to abstract your thought away from these pattern biases in isolation as to the representation in the brain.
The pattern / object is a very dispersed collection of micro “temporal fragments” that is by association voted into existence, not necessarily as a single column concept that we would (conveniently) like to exist as a coffee cup. This mostly fits with the thousand brains but I completely disagree with “where” input as the “where” is just one of many associative correlated inputs, not a specific where, it’s just an associative input, one of many. Sensory “Where” (place/grid column associations) is just another associative concept as to the word “shop” or “guess”. Everything is just a concept (usually tagged with a word pattern for communication - “if it is a desirable effect”) and the shear scale of the brain is what we have problems in conceptually dealing with. Same goes for our inability to comprehend space in relation to the nearest star, let alone another galaxy, it’s just the way our brains work from evolution only having to deal with an environment what we can physically move in.
How we go from parallel (occipital/auditory/sensory/etc) to serial (temporal) to parallel (cortex activation wave) to serial (broca) processing internally is something that is biologically awkward to hold in a transitory state…
You can’t magically create an information bus for a particular purpose that is not an associative activated mechanism. Synapses need a trigger to be created and destroyed or inhibited and the reason for explicit information transfer is where I think you have an issue. Dreaming/REM is a separate interesting process that may “share” information between columns but I think it’s more correlated “association leakage” rather than intentional information transfer. Different close associated correlation amplification with intentional purpose ?
My basic thought would be avoid the bias trap of seeking correlation and building a discovery away from what it does. Columns are a data compression object like RLE.
Maybe cortical columns are the equivalent of transistors in a CPU where we don’t really need to know the quantum mechanics of electron tunnelling to understand what a column “can” do or “does” functionally and then re-look at the overall architecture. Building a computer from transistors is far easier than building a computer from quantum electrodynamics ground up as can be seen from the over half century gap in relative progress. True a quantum computer will make us look like cavemen, but we can still use fire in the interim.
The point made at 19:50 between the cerebellum (animal) instinctual pattern activation to the more complex temporal pattern overridable process in the cortex is not to be missed or misunderstood as to existing purely in the cortex. “Instincts” may dissolve/migrate to the cerebellum and this adds sort of an additional layer of data compression in a dispersed memory array of temporal events.
Maybe I’m wrong, and very likely so, but hopefully a good disruptive thought initiator.
