Emerging technologies

Question

On May the 1st 1994, I had the chance to be published on a local IT magazine "PC USERS".

It was an special issue that one, as it contained all articles written by the readers.
I don't remember well, but I've sent a couple of articles about viruses, I think. Opinion related, nothing fancy. In fact, the published article was a crossword containing IT related terms. Imaging something less fancy than that. Anyway, getting to my point, after you finished the crossword, the central legend was VIRTUAL REALITY.
I'm talking about the mid 90's. I've used this, for example: http://www.gadgethelpline.com/wp-content/uploads/2014/12/vrheadset.jpg
VR was something like The Lawnmower Man (1992) [http://www.imdb.com/title/tt0104692] flick, or even Johnny Mnemonic (1995) [http://www.imdb.com/title/tt0113481] thing, all pre-Matrix-VR to clue you in.
*Still*, we thought at the time that *that* was *it*. More than 20 years after, the concept is gaining power again, and, for the new generations who probably think that this is a *new* trend, it was a new trend way in time, and of course, before that too.
Now feeling myself mumbling like an old chap, let me ask you the following- Which of the current so called IT "Emerging Technologies" do you really think has a future?

5G cellular communications
Ambient intelligence
Artificial brain
Artificial general intelligence
Atomtronics
Augmented reality
Blockchain or distributed ledger technology
Carbon nanotube field-effect transistor
Civic technology
Counterparty (technology)
Cryptocurrency
DNA digital data storage
Exascale computing
Gesture recognition
Internet of Things
(Due SL max chars limit, I shall end on a second post)

Answer 1

Emerging memory technologies
Emerging magnetic data storage technologies
Fourth-generation optical discs (3D optical data storage, Holographic data storage)
General-purpose computing on graphics processing units
Exocortex
Li-Fi
Machine translation
Machine vision
Mobile collaboration and e-learning
Nanoradio
Optical computing
Quantum computing
Quantum cryptography
Radio-frequency identification
Semantic Web or answer machine
Smart speaker
Software-defined radio
Speech recognition
Subvocal recognition
Virtual Reality

I'm writing this after reading a bit about Blockchain, which I find myself a fascinating concept.
