Right. To be clear, the purpose of the article is not 'zounds, C and C++ have footguns!' but 'C and C++ have footguns – yeah, this is not exactly breaking news – but here is a hopefully helpful summary of where they are, why they exist, and what you can do to avoid them'.
If you are already satisfied you know how to avoid them, and you don't need any more help with that, then you are not the target audience, and should by all means ignore the article.
