Recent news (1) that brain functions can be translated to speech outside the human infrastructure is interesting. More generally, it is likely that most human senses can be replicated with inputs from the brain. As humans live a lot longer than their design life, their infrastructure is likely to fail before their brain. If the brain is still able to function, most outputs could be replicated outside the ill-designed body.
Humans have been struggling to optimize a horizon that is increasingly predictable. Their infrastructure was likely selected for long distance running, something that has become less useful in the modern context. But their brains, likely overdesigned for survival, seem to be robust, perhaps able to go twice the design life of the hardware. Hence, connecting the instruction set from the brain to outside systems may become necessary for the species to survive.
Lack of understanding of the brain has kept the humans guessing. It is likely that a brain is a quantum machine and that is enigmatic in the status-quo. In the long run, pickled brains could store and process information in such a way that the network can be expanded exponentially. The failure of the infrastructure should not be considered final, as long as the brain is able to function, outside its enclosure.
We could create a new meaning to "plug and play." The brain appears to last a lot longer and conventional metrics of expiry may not be optimum. The human network could incorporate significantly more information than what contemporary societies allow.
