Sorry, didn't notice this thread continued... I'm actually getting old and grumpy. And I'm talking about common usage since I was an undergraduate taking AI courses 30+ years ago and surveying CS literature, some of which predated my courses by another 10-30 years... I recall one visiting professor who was an "AI researcher" at NASA, and his work was planners and optimizers for spacecraft operations. But getting back to the basic point: there is a semantic difference of having a grammatical article, which for others here carries more significance than you seem to admit. "Artificial intelligence" vs "An artificial intelligence".
