If you like higher level languages like C#, you are not going to like Zig, except the surface similarity in syntax.
not liking syntax is not enough reason not to use a language. It takes a few days to get over the unfamiliarity in syntax. concepts are much harder to learn.
What syntax are you looking for? If you want C syntax, D will be the closest (most valid C code is also valid D code). If you want Ruby syntax, there's Crystal. Zig feels more verbose to me. For example, there are no multiline comments and no operator overloading, which kind of got to me when I tried Zig. This is, of course, purely subjective. Some people like the Zig syntax.
True, but you mentioned Nim earlier, and this is a discussion of Zig, which hasn't even reached a stable release. D is an old, stable language that's still under heavy development. It's used by some companies and is able to support an in-person annual conference. I have no concerns about the code I write today working ten years from now.
There are more similarities in the lower level than you think. Once you start writing structs that use generics to specialize their allocator (as in, for really hands-on memory management), it starts looking similar, much like when you write portable SIMD code, which I should commend Zig for having the API for that is similar to .NET one.
Drupal is a heavy application for sure, but it's also used in a lot of very high-volume places (sometimes in ways that you might not expect - for instance, va.gov is (sorta) built with Drupal. As of a few years ago, all of the NBCUniversal sites were as well). It takes some TLC to get it running properly. The ancient version that this site is running (Drupal 4.6 it looks like - released in 2007) probably just can't handle it.
(full disclosure, I occasionally contribute to Drupal + work/worked on the sites mentioned above)
