Thanks for the link Paul. And yes, I read Musk's bio. But I'm definitely a user, not that great of a grasper of the convoluted tech involved. I tend to agree with some of the criticism of the article. I think there might have been more fanboy of Bitcoin than actual tech expertise on the part of the journalist. How much is actually known about what a quantum computer can actually do? What did you think of the article? Is there any such thing as unhackable?
