This line of reasoning is silly, because no one in their right mind would choose to use gdscript for any program that was not in Godot. You can't even type a nested array, among many other issues. That is because gdscript is a bad language objectively. It being part of Godot doesn't change that. Why would I choose to write my game, the thing that is very hard and will take years, in an objectively bad language? I would not choose that, because that doesn't make any sense to do. Writing code is like 90% of the work if I hire artists. I am not going to do 90% of years of work in a shitty language, because I don't have to do that, being a skilled developer in real languages.
So when people come out and defend gdscript for being not that bad, it's like, okay, but it's still really shitty compared to any normal language like C# or even Python. It is made by a game engine, used by thousands of people, instead of being made by gorillions of dollars poured into it by tech companies and used by millions of people. I'm just going to use good languages instead.
