It lasted 25 years, which might be surprising, that Americans would give up their American-ness for that long, but they were 'patriotic' enough to accept just a single approval by Congress of a super-Unconstitutional muddy Act on a long-term basis.
It seems the authority of the Act is waning now.
The new model is AI. The threat of escaped or rouge AIs, the use by citizens of AI. A new 911-like thing would likely be in the shape of some AI event as appalling as 911.
When?
Also, I'm not seeing how "AI" gets itself so deep into some new 9/11-ish event. The old 9/11 involved >75% Saudi nationals, 4 jet airplanes, and 2 skyscrapers - the all specific choices by the attackers. Except where it suited the government's interests - creepy machismo security for airline passengers - zero of those things became foci of major & ongoing government attention after the attack.
You can log me for a 'big event' forecast. I think one would have to have a faith exceeding the wildest religion to expect otherwise.
It will be EXTREMELY import (critical in the strongest sense) going forward, however, to remain acutely aware of censorship and manipulation masquerading as safety.
Edit: I should add, since we are in prediction territory: Expect a lot of pressure coming down on Open Source (and compute in general). No need to bash me for saying it -- just have patience.
