Blockchain and AI are the two extremities of the technology (centralized intelligence and decentralized applications).  

The intersection of these two births precision, that eliminates errors through encoded algorithm leaving audit trail that are traceable affecting almost all industries.

Many say that blockchain will do to traditional banking what the internet did to the media but the intersection of AI to blockchain will push traditional banking institutions hard as transaction can be done and traced without third party at even lower cost.

These Innovation will further disorientate the present Social structure, imagine Someone in Port Harcourt been able to purchase a commodity in Porto without fear leveraging on the audit trail of blockchain and the precision of AI algorithm.

Many might even risk leveraging on AI trading abilities,  I favor the use of AI to analyze market structures and and making mathematics forecast but the human trader picks up a strategy to execute the AI findings. 

• Lets say if y happens z will happen and in the process something different happens then one needs to figure out how to salvage the situation that where AI falls short  

Paradoxically AI will tend to be a big all, big time innovation as time flies replacing many but human will always be prevalent making those strategic decision at the final third, birthing and improving AI in the process.
