Second, the "hard part" of creating a script isn't the typing of words. Its the understanding of systems, data structures, how to manipulate all that to get the desired results ... the "Programming" of it.
Visual scripting DOES NOT change the programming aspect, in many cases it makes it harder since visual scripting tools are always far more limited than text based scripting so you often have to be more "clever" with how you do things.
How can I say they are always more limited?
Visual scripting tools write script for you, they are not black magic that is an alternative to code. They simply help you write code, they are thus always behind the current state of text based scripting or at best almost (but never quite) as complete.
