A bit off topic, but worth keeping as reference when someone complains about the GC,

John Carmack's answer regarding how he sees GC question on the Lex Fridman Podcast.

"It is only when you get into the tighest of the real time things that you start saying, no the GC is more cost than it has benefits for, but that is not 99.9+% of all software in the world..."

He eventually follows up with a discussion he had about the matter on Twitter, and how some developers cannot let go of the good old days fighting for each byte.

He might know a thing or two about high performance code.

Maybe an interview to bookmark and post on the regular GC discussion threads, as pinned answer.

That's kinda bullshit, it depends on the GC implementation

D's GC is not good for 99.99% "of all software in the world", it's wrong to say this, and is misleading

Java's ones are, because they offer multiple implementations that you can configure and the, they cover a wide range of use cases

D's GC is not the panacea, it's nice to have, but it's not something to brag about, specially when it STILL stop the world during collection, and is STILL not scalable

Go did it right by focusing on low latency, and parallelism, we should copy their GC

It's actually 69.420% of all software in the world

Exactly, hence why this quote is bullshit

Let's miss every opportunities to catch market shares

Discord switched to Rust, because they wanted to work in cool new toys, that was the actual reason, while they use Electron for their "desktop" app.

Meanwhile companies ship production quality firmware for IoT secure keys written in Go.

What we should promote more about D is the fact that

"GC is here when you need it, but you can also go raw when you need it, pragmatism allows D to be used for 99.9% of traditional softwares, but is also suitable for the remaining 0.1%"

And not just "We have a GC too, who needs to manage memory manually LOL"
