It kind of bounces back after the catastrophe that D1 vs D2 and Phobos vs Tango caused, but might be broken by AI bros trying to chase the vibe coding trend.

D seems unlikely to get a renaissance. These days languages are facing much stiffer competition, and D has never solved its fundamental problems:

It is a rudderless language, that struggles with fragmentation due to the hype-driven addition of half-baked and mutually incompatible paradigms, with a leadership that keeps driving away contributors.

I can’t see how any of this could change while Walter Bright is still in charge, but I also don’t see how the language could survive him stepping down as BDFL

Multiple in fact. D1 vs D2, Tango vs Phobos, mutable by default vs const by default (was minor, but allegedly lead to the existence of Rust), Adam D Ruppe leaving and forking the compiler (OpenD - might be useful to you depending on things), "let nazis code" (though DLF have not only backtracked on it but also set up some basic safety measures), etc. Can still recommend the language if you want a more C-style language and not OCaml with curly brackets, or if borrow checker is a dealbreaker for you in Rust.

The Wikipedia article for D links to this blog post which seems pretty damning.

There have been something where some developers left, but I don't remember it well enough to search for.

I think it's just a joke about slang aka D for Dick.

If nothing else, there's also OpenD, which might be better for you based on your requirements.
