Vitalik Buterin talks about synergies and I agree with him. For the past 3 years I've been trying to build a bridge between futurists (and transhumanist ideas) with blockchain enthusiasm. The idea of an exocortex is not new and as the article details it originates with the Memex but if you look at what a blockchain really is, it is a ledger which acts as an external accounting but can also be a type of memory. In fact there is a paper direct from the federal reserve which specifically says money is memory:  https://www.minneapolisfed.org/research/staff-reports/money-is-memory

The blockchain can act in a limited extent as a collective memory because of the consensus and the fact that everyone in theory contains the full copy of the blockchain. In practice there are of course some issues we see such as the limited ability to do governance under certain designs but this is changing with the DAO. Additionally I see some other trends happening and make the prediction that computation will be commoditized and tokenized along with other resources like storage. As this is happening we also are seeing VR coming of age, and the brain to computer interface is also slowly being worked on behind the scenes.

All of these technologies are in my opinion leading to a certain conclusion that governance itself is going digital, and that the most local form is a chip, and that chip could be a wearable or an implant depending on what people choose but this means the blockchain itself is something people will have the option to merge with in the transhumanist or cyborg sense.

I wrote about this topic of cyborgization before here: https://transpolitica.org/tag/cyborgization/

So in the case of a cyborg what is the ideal relationship a cyborg can have with a blockchain? Would the blockchain connect to their clothing? Probably. Would their health be continuously monitored by an implant? Probably and that too could be pinned to the blockchain. In fact there is already a continuous glucose monitor used by diabetics (ex: http://www.webmd.com/diabetes/guide/continuous-glucose-monitoring ) but in the future hopefully we will not only have continuous monitoring for diseased patients but for patients who want to slow their aging or prevent illness. Again these are transhumanist concepts but they are synergetic with decentralization and the blockchain.

A lot of the stuff people have spent years talking about can now be built. The DAO as a concept has been discussed for many years in futurist circles and certain books even have concepts which resemble a DAC. The exocortex is one of these concepts which have been discussed for years but only now is the technology at the point where we can begin building one, and the blockchain technologies being developed now means we can do Google decentralized.
