Why isn't the game industry moving to rust?

Someone in that industry can perhaps speak to it, but I have two cents of perspective...

I have helped a young person with gamedev interests try to learn rust (on Windows). They've learned some rust, but the graphics+Windows libraries and primitives to work with are not very good nor straightforward, even with AI assistance. Besides weakness in the gaming/rendering domain, there seemed to be some very real versioning/dependency hell that also didn't help.

It's massively easier to make progress on even just a 2D game with something like GDScript-based Godot (or Unity or...).

It seems like you're comparing "start from scratch in rust" to "start with an existing game engine in some other language". That's not really a fair comparison. there are popular game engines in rust (although i think they're mostly smaller/more niche then something like unity or godot), bevy comes to mind.
