Thanks I enjoyed your article.

Well, none of us knows whats going to happen; so far every technical revolution has created more work, its just different work. However with the capabilities of technology that is being developed now, I do see mass unemployment as a significant issue.

Just look at block-chain and crypto-currency. Disintermediation (the removal of intermediaries) is where block-chain really adds value.
I was presenting SolarCoin and ElectriCChain at a major UK solar energy exhibition yesterday, I showed the audience that with a few tools that are already available in the crypto-sphere, we can take out all of the middle-men, banks, and centralized power infrastructure, and move to localized, decentralized micro-grids. Removing all those intermediaries make the processes much more efficient, but there are a lot of companies and people that are going onto the redundancy list if I am right about that future.
As ususal Im conflicted about whether its to be persued or avoided.
