Tech can be a force for good, and we need to have strong collaboration between government and the tech business. AI and blockchain are strong enablers, they will significantly change how we interact with the world. There is a strong belief in that humankind can solve it's big problems. The number of good people vastly exceeds the number of bad ones, so we just have to keep in mind our violent history and build on the strong foundations of peace and prosperity to build a great future.
There are a few technologies that are expected to bring new waves of disruption. What will cause disruption will not be the technologies in themselves, but the application of them on real and tangible business problems. The reason to gauge they are ripe for wider use, is that we start to see user interfaces to them. The techologies are machine learning (already here), deep learning AI (getting there) and blockchain technologies (nearing faster than we think!).
