About garbage collection: Are there a lot of Unity/Godot devs unaware that their engines are using GC? I would assume they'd have accepted the cost of GC already. Unreal devs I can understand having an issue with it though.

If you spend a week in these engines you're well aware of the garbage collector.
https://unity.com/ leads with demos.
https://kaijuengine.org/ leads with a block of text claiming it renders cubes faster than Unity.

Can you explain? AFAIK Godot uses C++ under the hood which does not have garbage collection. Other languages such as C# and GDScript use bindings.
Funnily enough whilst trying to Google gdscript and godot, I found this post I wrote in 2018 (subcomments mention gdscript and gc).
I don't understand why they're calling out the FPS of an empty scene as a useful number compared to Unity though. Ignoring that this engine will have a fraction of the features of Unity (the likely reason for the FPS number in the first place), it's just a useless benchmark because it's an empty scene. `while (true) {}` will get you the same thing.
I'd wish they'd highlight how the engine helps you make a game rather than arbitrary performance numbers on microbenchmarks that don't generalize to a real game project. You can absolutely be faster than Unity, but "9 times faster than Unity out of the box" is not a number people should take seriously without the context of where the number comes from.
I wish them well though. I'm always interested to see more work in implementing engines in GC languages. I'm personally quite interested to see what can be done in modern GC languages like Go or (modern) C# which provide lots of tools to limit GC pressure. Being able to write C-like code where needed in an otherwise managed runtime is a really powerful tool that can provide a best-of-both-worlds environment.
With such an outrageous and unfounded statement, I'm just going to assume the project isn't worth taking seriously.
Make a real game first, and then we'll talk.

Other languages that bind into the engine do this too, (C++, SwiftGodot, Rust-Godot)
C# obviously does, Miguel de Icaza actually started SwiftGodot because he (ironically) ended up hating GC pauses after promoting C# for so long

The times of pure manual memory management game engines, across all layers of what requires to draw a frame are long gone.
Naturally someone is going to point out some game engine using compiled C dynamic libraries for scripting, those are the exception.

GDScript in Godot doesn't use GC, it uses reference counting and doesn't "stop the world".

Reference counting is a GC algorithm from CS point of view, as looking into any worthwhile reference will show.
