Mostly lies and marketing. The so called AI of Watson to win Jeopardy was unrelated to the Watson IBM sold for Medicine, which didn't work.
Most of the so called success of AI is pattern-matching of human curated work branded as AI.
The LLM, on Cloud or local is even less use.
"Deep Learning" is a lie. AI Jargon along with terms like Machine Learning and Neural Networks (which aren't).
I started my study of programming due to interest in AI, which was marketed as Expert Systems from the late 1980s.
AI didn't do any of the things on your list. Pattern matching aided by computer databases and software from human curated sources achieved the results. Also none of that list applies to how LLM work.
AI after 60 years is still a toy, now being hyped like cryptocoins and NFT. Analysis suggests this is hype bubble and will fail as the costs of builing the LLM and feeding the data exceed any income possible, which is not even considering that the productivity gains claimed to sell it are by the people selling and are lies.
