I know it's not as complicated as C++ but it sure seems like they're in a rush to get there :) . Modern (post c++14) covers most of my criticisms of c++ for my daily driver. I still poke at Rust because I really love statically typed languages :)
I've been very surprised by Rust's complexity. Some of it seems to be being hidden over time (as well as adding new features) but its syntax at any given moment is generally more complex than C++.
I’m not being contrarian, but I have only been following Zig in passing. Can you give a few example of the increase in complexity, I am genuinely curious. Zig seems, to my eyes at least, to have done an admirable job of remaining simple when compared to the behemoth that is C++, of any vintage (but especially post C++03).
