Yes, it is literally true in the field of computer science, but it’s being thrown around loosey goosey in a way that does not align with how it would be used in a technical sense, at least my in experience, though it’s been 15 years since I was in school, and 5 years since I did my last machine learning work in robotics.
The field of AI contains ML, but “an AI,” singular, as used in this headline, is a generalized intelligence. When you write a headline “AI is building…” that’s not the technically correct usage I am used to.
But my point is that suddenly what any industry used to call machine learning and has been doing for a decade or more is getting puff pieces as part of the AI hype because of LLMs. Anyone so much a thinking about a markov chain is changing their marketing copy to be about how they’re an AI-driven company.
