Article III, Section 3, Clause 1 says:
Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the testimony of two Witnesses to the same overt Act, or on Confession in open Court.
It's a fairly narrow definition. I haven't found any cases where the USSC defines "enemy" but, given the preceding sentence, it looks like the heavily implied definition is, "Members of a nation that is at war with the United States."
Officially, the US has only been at war 5 times. The last one was WW II.
You're right. They're not LLMs and they're not particularly new.
The main new part is that new techniques in AI and better hardware means that we can get better answers than we used to be able to get. Many people also realize that there's a lot of potential to develop systems that are much better at answering those questions.
So when people ask, "Why are companies investing in AI when customers hate AI." Part of the answer is that they're investing in something different than what most people think of when they hear "AI".
