Using it today for identity management is ridiculous. It's a brand new technology and will take time to fully develop.

Using brand new kind of liberally here.

The idea of a blockchain is more than 20 years old, with the first popular implementation, Bitcoin, being 9 years old.

That's the same year the iPhone 3G came out. So if you want to argue "brand new" that's where you've got to start.
