This was a really good summary of what Rust feels like in my opinion. I’m still a beginner myself but I recognize what this article is saying very much.
The hacker news comments are as usual very good too:

It’s not that the author picked Rust for scripting. All Rust game engines (e.g. Bevy) use Rust as the scripting language.
Compare this with Godot, which is implemented in C++, but supports GDScript and many other languages for scripting.
Also, only supporting Rust is not considered a limitation, but a feature here. Bevy’s ECS is tied up with Rust’s trait system, therefore it’s impossible to use a different language.
So if Rust as a system programming language should not be used for game scripting, then projects like Bevy are fundamentally flawed. The author is willing to go there, but I don’t know if many people would go that far.
There could be a Godot-like engine written in Rust that supports easier scripting languages, but I think that space is not explored due to the fact that Godot already exists.
It’s also worth noting that before bevy, there was a rust game engine called Amethyst, which was planning on using a scripting language for gameplay code. Not having to use a scripting language, but getting to use rust instead, was one of the big selling points of Bevy overr Amethyst.
Bevy has added runtime-defined systems and components to enable scripting integration in recent updates.
Completely agree with all those points.
The author seems to be a enthusiastic coder and made several game engines in Rust. I’m not sure why they didn’t hook up some hot-reloadable scripting to their engine, call it good, and build games. Probably less work than writing this very long article :)
Yeah I would probably not use Bevy either if the only option is to write all gameplay code in Rust. It doesn’t seem like the best tool for the job.
