i agree with the title, but not with the article. All the things listed in the article can be learned outside of a CS degree. What a CS degree does is force you to learn the academic which gives you the foundation to work at FAANG or some other company that has high [principal] engineering levels, or even just the awareness of knowing what you don't know to round out your skillset post school.
Having said that, a CS degree isn't necessary, just better under the premise that knowing more is better than not knowing more.
