It depends a lot on how we perceive "intelligence". It's a lot more vague of a term than most, so people have very different views of it. Some people might have the idea of it meaning the response to stimuli & the output (language or art or any other form) being indistinguishable from humans. But many people may also agree that whales/dolphins have the same level of, or superior, "intelligence" to humans. The term is too vague to really prescribe with confidence, and more importantly people often use it to mean many completely different concepts ("intelligence" as a measurable/quantifiable property of either how quickly/efficiently a being can learn or use knowledge or more vaguely its "capacity to reason", "intelligence" as the idea of "consciousness" in general, "intelligence" to refer to amount of knowledge/experience one currently has or can memorize, etc.)

In computer science "artificial intelligence" has always simply referred to a program making decisions based on input. There was never any bar to reach for how "complex" it had to be to be considered AI. That's why minecraft zombies or shitty FPS bots are "AI", or a simple algorithm made to beat table games are "AI", even though clearly they're not all that smart and don't even "learn".
