The article is about creating a potential successor to C++ in the same way JavaScript lead to TypeScript, or Java lead to Kotlin, or C lead to C++, and in giving those examples immediately undermining its own thought because none of those
replaced the thing they came out of. Heck looking at whose still writing new code bases in what, C++ didn't even replace C, and Swift didn't replace Objective C. C++ and Switft just became "more dominant".
So based on the article's own observation: no, of course not. The more interesting question is "will it stand on its own?" to which the answer is "only if it actually solves so many problems with the thing it's trying to supplant that it makes sense to give it a serious try".
And C++ just... doesn't have that many real problems. It has a lot of irks, but the problems people run into are problems that others already solved, a thousand times, over the last half century, in many different ways for many different iterations of the language.
Pretending you can replace C++ is like pretending you can replace cars. Not just "create EVs" but straight up replace cars. Good luck, you won't succeed if that's your goal, so hopefully you realise you need to focus on making a decent language that some folks might consider using instead of C++ for some of their work, instead of creating "the successor to C++".
