As should C. C++ is staying relevant (among other reasons) because it embeds C as a(n almost) subset in a natural way. To understand why C++ is remaining relevant, one must understand why C is remaining relevant. It has little to do with the language itself. As long as the creators of other languages, including so-called C "successor" languages, keep giving zero shits about language interoperability and prefer to play in their little sandboxes that they've created for themselves instead of collaborating on creating a language-agnostic ABI, the C ABI will remain the ABI Franca, so C will stay relevant. As long as C (and C++) are the only languages that you can compile and link the way you see fit as opposed to caving in to some my-way-or-the-highway language-specific "fully integrated" dependency manager and build system, C will stay relevant. As long as this lack of vision, this pathological shortsightedness, and this complete disinterest in taking any steps whatsoever to unseat C from its privileged niche and create an ecosystem in which "successor" languages can compete with C on a level playing field continues to dominate the entire industry and every single "language" community in existence, C will stay relevant.
