1. Big Data
Our data will be as big as we can afford it. Large IT vendors have almost succeeded to convince us that the budgets should accommodate data and not the other way around.
2. Internet of Things
Too wide and vague term extended to many things that worked long before this term came to existence. What happened to embedded systems? Are they now Internet of Things?
3. Additive manufacturing aka 3d printing
Not much in use in real life manufacturing besides printing very costly demo toys on very expensive machines at trade shows and exhibitions.
Do not add much functionality at reasonable price beyond what we already have in our smartphones.
5. Smart home
Most of our homes are still wonderfully stupid which doesn’t make them any less usable, habitable, pleasant or secure, maybe even more secure.
