On “Why are all the binaries I make with cargo build --release a minimum 3.3 Mb? Isn't that a bit big?”

Also related to this: link to this video - Before Main: How Executables Work on Linux with Ryan Levick and the author of the article you linked. I think the first 20 or 30 minutes is about making the program smaller, based on this article.
