New game developers picking up things for the first time will hear about Godot's advantages and choose it over Unity and Unreal, since it's arguably a better fit for where they're at. Over five to ten years, this will have a non-negligible impact on the pipeline of engineers and games.

Apple also has a huge beef with Epic Games, and I wouldn't put it past them to give giant grants to Godot. They can make use of the output for their own needs.
