I think, the community of godot will decide...
It’s will depends on how the community will used most c# or gdscript
In my opinion, support multiple scripting languages will affect the community and getting support support from others.
Look at unity , in the past , Boo, JavaScript , C#
But now, only c#, no doubt godot will face same issue
One more thing, I think anyone know gdscript very well , will keep using it
But anyone coming from unity or other game engine
May see c# better, since no need to learn, the basics , dive in docs. , and start coding
For me, I really disagree the multiple scripting language
Because it’s will end with one :)
So learn from unity mistakes better
Good luck everybody
