AI Definitions, Discourse and Academic Resources

I am doing my thesis related to AI and one thing I have noticed right off the bat is the constant discourse over something as simple as the definition of AI. Not only is there discourse for almost every aspect of it or what can even be classified as "intelligence", but there is also an ever changing landscape, with limitations, definitions and applications of AI constantly changing. What would you all consider "Artificial Intelligence"? Is it really "intelligent" if AI (like ChatGPT) are just prediction models? What seems to be most debated in the AI landscape nowadays? I would also really appreciate if anyone has any strictly academic resources regarding AI (university lectures, theoretical studies etc).
