Weird strawman. Those tools all run on terminals. IDEs use tools that run on terminals.
Teams can use a combination of different IDEs and run the tools at different levels or their pipelines, which necessitate that they be automatable (and not GUI only).
You're missing the point, they aren't saying "your development process should never involve a terminal" but rather "you don't necessarily have to use this bare-bones setup which happens to be terminal based"
