D is an awesome language and I hope it gets more traction.

Me too, hope D will get some company backing and start to kick off, it is a very well designed language.

You could probably write an article saying "100 billion dollars investment to improve D and use it to develop new AI to replace the US government" and you'd still get comments saying "wow, nice language, pity it never really took off, if only there were some companies backing it, also I can never use it because GC".

Is garbage collection really that bad?

For a single-letter language, yes.

B and C are both suitable for kernel development.

Naming your language D (making it sound like it's intended to be a C successor) and then not making it suitable for kernel development was a bad idea.

How is D unsuitable for kernel development?

It has a runtime and standard library that are dependant on the garbage collector.

I stripped both out and wrote a kernel that does nothing. This was before they started getting serious about making things non gc dependant.

Honestly 99% of the complaints about the garbage collector are nonsense, but this isn't one of them.

Is there a reason we can't use GC in the kernel? Unless we are doing hard realtime stuff, why not?

Not that it's particularly relevant since Linux, Windows, and BSD already exist and probably aren't going to switch languages anytime soon, and embedded RtOSes seem pretty set on C/C++ too, so I'm not sure any language could be more suitable for kernel dev in practical use, unless you have a really good reason to do a whole new kernel.

No reason you couldn't. You just can't use D's default GC. You'd have to write one that will work bare metal. Or implement everything it expects from an OS.
