The author didn't have a CS degree so it's not classic gatekeeping: "For the majority of my career, I neither had a formal, rigorous computer science education...". The author also directly addresses the parent poster's viewpoint: "If I had to categorize the 'no need for education, no need for algorithms' crowd of our field, they’d fall into three categories: They either focus on the wrong things when developing software, they have a very shallow knowledge and lack of regard of how difficult good engineering is, or they’re utterly clueless and rely on good soft skills and politics."

Personally I agree that a CS degree isn't needed for most software jobs because frameworks and libraries hide most of the gnarly CS stuff. But those are the software jobs least likely to survive adoption of LLM-based software development.
