When meeting my company's Head of Blockchain (not sure if the pun is intended) a while ago, I asked him if git would qualify as blockchain technology. He replied that "blockchain is not a technology, It's a paradigm shift". Literally. That statement was so absurd I didn't even know what to say, so it worked out well for him.
This is exactly what's driving my skepticism. The people who I've met who are most vocal about "blockchain" are also the ones who know little to nothing about the algorithm itself (and algorithms in general).
That is exactly the kind of thing I would expect to hear from a "Head of Blockchain". Your company made a great hire, and they will clearly push the boundaries of marketing bullshit with regard to blockchain.
