But it doesn't have to be and it shouldn't. Rust also isn't a paradigm shift, it "just" solved static memory safety (admittedly a great engineering feat) but other languages solved memory safety too decades ago, just with more of it happening at runtime.
But in many other areas Rust copied too many bad ideas from C++ (and many of those "other things" Zig already does much better than Rust - but different people will have vastly different opinions about whether one solution is actually better than another - so discussions about those features usually run in circles).
There shouldn't be a single language that solves all problems - this will just result in stagnation, it's much better to have many languages to pick from - and even if they just differ in personal opinions of the language author of how to do things or entirely subjective 'syntax sugar' features. Competition is good, monocultures are bad.
> The most important consideration in any software project is managing architectural complexity
No language will help you managing "architectural complexity" in any meaningful way except by imposing tons of arbitrary restrictions which then get in the way for smaller projects that don't need much "architecture". We have plenty of "Enterprise-scale languages" already (Java, C#, Rust, C++, ...), what we need is more languages for small teams that don't get in the way of just getting shit done, since the really interesting and innovative stuff doesn't happen in enterprise environments but in small 'basement and bedroom teams' :)
