I have been reading about this new language for a while. It's a C competitor, very slim language with very interesting choices, like supporting cross platform compilation out of the box, supports compiling C/C++ code (and can be used as a drop in replacement for C) to the point in can be used as replacement of (c)make and executables are very small.
But, like all languages, adoption is what makes the difference. And we don't know how it goes.
Is anyone actually using Zig right now? Any thoughts?
Good interop was a requirement for widespread adoption, but not the reason why programmers want to use it. There's also null safety, a much nicer syntax, custom DSLs, sealed classes, type inference, data classes, named and optional arguments, template strings, multi-line strings, computed properties, arbitrary-arity function types, delegation, custom operators, operator overloading, structural equality, destructuring, extension methods, inline functions and non-local control flow, reified types, ...
Some of these features have since been added to Java.
I wasn't trying to diminish the value of Kotlin, my point was that interop makes it so easy to stealth insert it into legacy java codebase, and that probably contributed heavily to it's success?
Language adoption is a multi-part problem, you ideally need good interop (or upgrade path) and your language needs to also be compelling enough to upgrade to. Zig certain seems to have the former, I'm not personally sold on the latter, but it certainly sounds like it might have some compelling features.
