alt Hacker NewsStill doesn't have full static typing support to my knowledge, which is a dealbreaker to me.
The other things are that it just has less support for structuring your code in different ways, and of course the performance is vastly worse. My game does some state space exploration for the enemy AI, so having code that runs an order of magnitude slower just doesn't work for me.
It has support for typing Arrays and Dictionaries these days. Yes, nested Arrays are still a problem but I am sure they will get to it.
As for performance well the GDExtension support has also gotten much better. You can always go down to C++, Rust, Nim, Zig or whatever. It is really easy to set up.
