Blockchain is just glorified check-sums (on money value and content); I don't see how it allows things that couldn't be done before. Was check-sum tech simply too crappy or hack-able back then? Maybe I'm missing something.
Detox = bouncer/moderator. Again, I don't see what's new technology-wise. It's a business decision to have scrubbers of some kind, and it takes resources to scrub well. I could see it as a "business trend" or customer preference trend maybe, but typically the pendulum swings back and forth on such.
D. Blockchain - I'd say the blockchain is overhyped by the mainstream but severely underappreciated by Silicon Valley types. It works, it's fundamentally novel. Money is a big deal and this changes money as we know it. A huge challenge to governments and legal systems. It has this 90s Internet feel to it.
H. Detox - Having a safe world where you can trust people is a catalyst for all kinds of progress.
J. Dark data - It works and is underutilized.
Hype:
A. AI - It's great just don't see us hitting the Kurzweilian hypergrowth.
C. IOT - Mostly has to do with improving the legacy-world. Boring.
B. Microservices - whatever.
