Are "Senior" titles meaningless in many companies? Absolutely. But they also matter in many others.
It seems as though the author's "juniorness" is showing through while writing this. In particular, the assertion that "programming skill is the most important skill for senior developer". I'm not sure that's true. You cannot write code in a vacuum; software development requires communication and understanding of the business to ensure you're solving the right problem. Doesn't matter how great your code is, if you write a solution to the wrong problem, you provide zero value. At companies where seniority is done well (FAANG, etc.) your performance is measured not just on the quality of your code, but the impact you provide to the business: this includes code quality, but also working on projects that matter to the bottom line of the business, enabling teammates to do their best work, bringing in new people, basically acting as a multiplier force.
