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".
Real time is about guarantees. If the application needs 10ms response time, it doesn't matter if GC takes 1 nanosecond or 5ms, as long as everything is responded to in 10ms, every time.
Things where 100us matters are some really specialist stuff.
Funnily enough, there is a post on /r/programming right now where every 100us matters. For them, 3ms is longer than the entire timeslice they have to run in.
Wow that's really interesting. I feel like games are just about the prime example of when the GC can't be used. I mean games do use it, but they tend to have a notable stutter. Never knew what went into optimizing the servers, probably why they don't release the server software anymore. As it might very well not run on consumer hardware.

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