I think AI must be built on top of blockchain, because the power that it gives to the inventor is enormous, and as we know, big power corrupts. If general AI is born in consensus-based environment we can use 51% attack against it (in case something goes wrong).

AI will change everything. We can't even imagine all implications now.

AI is already better than humans in trading (especially in day-trading).

99% of all human skills will be worthless in the near future (10-20 years). Don't waste time polishing your skills, instead think how you can apply AI in your field.

So, for us, who want to succeed in this new world it's better to keep robots as best friends.
