It's shit on because it is not actually AI as the general public tends to use the term. This isn't Data from Star Trek, or anything even approaching Asimov's three laws.
The immediate defense against this statement is people going into mental gymnastics and hand waving about "well we don't have a formal definition for intelligence so you can't say they aren't" which is just... nonsense rhetorically because the inverse would be true as well. Can't label something as intelligent if we have no formal definition either. Or they point at various arbitrary tests that ChatGPT has passed and claim that clearly something without intelligence could never have passed the bar exam, in complete and utter ignorance of how LLMs are suited to those types of problem domains.
Also, I find that anyone bringing up the limitations and dangers is immediately lumped into this "AI haters" group like belief in AI is some sort of black and white religion or requires some sort of idealogical purity. Like having honest conversations about these systems' problems intrinsically means you want them to fail. That's BS.
Machine Learning and Large Language Models are amazing, they're game changing, but they aren't magical panaceas and they aren't even an approximation of intelligence despite appearances. LLMs are especially dangerous because of how intelligent they appear to a layperson, which is why we see everyone rushing to apply them to entirely non-fitting use cases as a race to be the first to make the appearance of success and suck down those juicy VC bux.
Anyone trying to say different isn't familiar with the field or is trying to sell you something. It's the classic case of the difference between tech developers/workers and tech news outlets/enthusiasts.
The frustrating part is that people caught up in the hype train of AI will say the same thing: "You just don't understand!" But then they'll start citing the unproven potential future that is being bandied around by people who want to keep you reading their publication or who want to sell you something, not any technical details of how these (amazing) tools function.
At least in my opinion that's where the negativity comes from.
