A digital currency issued by a central bank would be a global target for cyber attacks, cyber counterfeiting, and cyber theft.
If nothing else, the cyber attacks that occurred during the 2016 presidential election have laid bare the very real vulnerabilities that exist across our government and the private sector. Imagine the harm that could be done if our enemies ever hack into the Department of Defense or Homeland Security.
At times, it feels like I'm being cyber bullied.
Every major player is working on this technology of artificial intelligence. As of now, it's benign... but I would say that the day is not far off when artificial intelligence as applied to cyber warfare becomes a threat to everybody.
