> 2.It felt uncomfortable that they spoke as if Rust prevents things that could actually be handled by Zig's style guide.
"Handled by Zig's style guide" ends up as "Don't make mistakes" which is entirely useless advice. C++ spent years trying to make out that this constitutes useful guidance before gradually accepting that people aren't in fact going to stop making mistakes, you need to provide a better language and tools.
I agree with some points as well. In fact, the OP argues that sufficient engineering attention can solve the problem, but I think that's only theoretical in reality, it's difficult. It's like C programmers claiming that undefined behavior is manageable.
