AI, blockchain and 5G: The top tech trends you need to know

The hype around artificial intelligence is at its peak, while those interested in blockchain might be heading for disillusionment. That's according to Gartner's annual Hype Cycle, which tracks the progress of emerging technology trends, from early innovation to becoming a household must-have. Deep learning and machine learning are at what it calls the "peak of inflated expectation", but are just two to five years away from mainstream adoption. Cognitive computing is also at peak hype, but up to 10 years away, while general artificial intelligence remains more than a decade away and is still at the stage of early innovation. Mainstream blockchain technology, which is being tested everywhere from finance to food chains, remains between five and 10 years away.
