No, machine learning is not AI. And Apple hasn’t had AI. Apple has had a dumb assistant and some machine learning that can at best recognize simple patterns.
AI is exactly what it says: artificial intelligence. Modern LLMs like ChatGPT are new. Machine Learning is a framework of rote processing but not understanding. AI understands things and can interpret and create things. Languages, art, movies, reports, Emails, etc.
It’s not even close. The fact that Apple is trying to partner with ChatGPT to bake that into their OSes tells people all they need to know about Apple and AI: they screwed up, and missed the mark and are now playing catch up, needing someone else’s technology because they have nothing of note.
