There are certain “stages” and types of AI. To call it a machine thing in some manner is to simplistic I think, anyways, of course, at the current state there is no “super advanced” AI (that’s why I said "to some extend) and the government is definitely not the only one developing it. It’s going to take some time indeed to progress to a higher a level. And yeah… There won’t be another whistle blower like Snowden anytime soon.
