Well, it might be a rational view for the author, but for me that's like saying "I no longer like cooking, because there are companies providing the recipes I like as ready-made meals", or "I no longer play my instruments and make music, because there are machines which can create the music I like"; both topic apply to me personally, and I wouldn't agree to the statements. I still like to design and implement systems, make clever architectures and solve tricky problems. Why should I care if other people use LLMs to do so?
