Digital identity management using sophisticated cryptography will be increasingly important in a lot of contexts in addition to this in the future. At least I hope so. The current mess we're in is a truly sad state of affairs with the sensitive personal information of over 100 million people being stolen from a centralized data center by criminals in a recent data breach in the Equifax hack, for example. I've talked to a number of people about this and I've been shocked by a lot of people even in IT being totally laid back about the catastrophic weakness of data security and identity ownership in today's world.
