You can give GPT-4 some data and ask it to make a hypothesis to explain it, give it tools to test the hypothesis, and have it try to establish causation. You can literally do that now quite easily with ChatGPT abilities like plugins and it will prove the premise of the article false.
An interesting contrast can be drawn between this article and a criticism like Yann Lecun's. In that his actually has substance. https://youtu.be/DokLw1tILlw Although he is also wrong about the capabilities of LLMs.
Certainly LLMs are not the end of AI research. They have various types of deficiencies and some missing capabilities that humans have. And are not alive.
But GPT-4 can definitely complete scientific experiments.
