I disagree with this post and with Stallman.
LLMs are AI. What people are actually confused about is what AI is and what the difference between AI and AGI is.
There is no universal definition for AI, but multiple definitions which are mostly very similar: AI is the ability of a software system to perform tasks that typically would involve human intelligence like learning, problem solving, decision making, etc. Since the basic idea is basically that artificial intelligence imitates human intelligence, we would need a universal definition of human intelligence - which we don't have.
Since this definition is rather broad, there is an additional classification: ANI, artificial narrow intelligence, or weak AI, is an intelligence inferior to human intelligence, which operates purely rule-based and for specific, narrow use cases. This is what LLMs, self-driving cars, assistants like Siri or Alexa fall into. AGI, artificial general intelligence, or strong AI, is an intelligence equal to or comparable to human intelligence, which operates autonomously, based on its perception and knowledge. It can transfer past knowledge to new situations, and learn. It's a theoretical construct, that we have not achieved yet, and no one knows when or if we will even achieve that, and unfortunately also one of the first things people think about when AI is mentioned. ASI, artificial super intelligence, is basically an AGI but with an intelligence that is superior to a human in all aspects. It's basically the apex predator of all AI, it's better, smarter, faster in anything than a human could ever be. Even more theoretical.
Saying LLMs are not AI is plain wrong, and if our goal is a realistic, proper way of working with AI, we shouldn't be doing the same as the tech bros.
