More like the companies that jumped into D versus Rust, D only had Facebook and Remedy Games toy a bit with it.

Many of us believe on automatic memory management for systems programming, having used quite a few in such scenarios, so that is already one thing that D does better than Rust.

There is the GC phobia, mostly by folks that don't get not all GCs were born alike, and just like you need to pick and chose your malloc()/free() implementation depending on the scenario, there are many ways to implement a GC, and having a GC doesn't preclude having value types, stack and global memory segment allocation.

D has compile time reflection, and compile time metaprogramming is much easier to use than Rust macros, and it does compile time execution as well.

And the compile times! It is like using Turbo Pascal, Delphi,... even thought the language is like C++ in capabilities. Yet another proof complexity doesn't imply slow compile natives in a native systems language.

For me, C# and Swift replace the tasks at work were I in the past could have reached for D instead, mostly due to who is behind those languages, and I don't want to be that guy that leaves and is the one that knew the stack.

The problem is the term "systems programming". For some, it's kernels and device drivers. For some, it's embedded real-time systems. For some, it's databases, game engines, compilers, language run-times, whatever.

There is no GC that could possibly handle all these use-cases.

But there could be a smoother path between having a GC and having no GC.

Right now, you'd have to switch languages.

But in a Great Language you'd just have to refactor some code.

Except there is, only among GC-haters there is not.

People forget there isn't ONE GC, rather several of possible implementations depending on the use case.

Java Real-Time GC implementations are quite capable to power weapon targeting systems in the battlefield, where a failure causes the wrong side to die.

Aonix is nowadays owned by PTC, and there are other companies in the field offering similar implementations.

Look, when someone says "There's no thing that could handle A,B,C, and D at the same time", answering "But there's one handling B" is not very convincing.

(Also, what's with this stupid "hater" thing, it's garbage collection we're talking about, not war crimes)

		It is, because there isn't a single language that is an hammer for all types of nails. It isn't stupid, it is the reality of how many behave for decades. Thankfully, that issue has been slowly sorting out throughout generation replacement. I already enjoy that nowadays we already have reached a point in some platforms where the old ways are nowadays quite constrained to a few scenarios and that's it.
