Come on now. You know he's not talking about small machine learning models or protein folding programs. When people talk about AI in this day and age they are talking about generative AI. All of the articles he links when bringing up common criticisms are about generative AI.
I too can hypothetically conceive of generative AI that isn't harmful and wasteful and dangerous, but that's not what we have. It's disingenuous to dismiss his opinion because the technology that you imagine is so wonderful.
