There are lots of technologies that attract our attention – and money – these days. We're obsessed with blockchain, cryptocurrency, IOT, big data analytics, cybersecurity3-D printing and drones. We're excited about virtual reality, augmented reality and mixed reality. We love talking about driverless cars, ships and planes. We can't wait for 5G and Wi-Fi domes that solve all of our network access problems; and while we're getting a little worried about social media and privacy, we're still addicted to our ever-more-powerful smartphones.
