The definition of “AI” is fuzzy and keeps changing. Basically when an AI use case becomes solved and widespread it stopped being seen as AI.
Face recognition, OCR, speech recognition, all those used to be considered AI but now they’re just an app on your phone.
I’m sure in a few years we’ll stop thinking about text generation as AI, but just one more tool we can leverage.
There is no clear definition of “real AI”.
Those are all still AI. Scientists still have a functional definition that includes these plus more scripted AI like in video games.
Essentially, any algorithm that learns and acts on information that has not been explicitly programmed is considered AI.
