When an actor follows a script and after some takes the director says to improvise, and you think the result is good, umm guess what dipshit, that was merely substituting some parts of the script for something else.
When a cook improvises, ooh you think that is new, no that's just substituting some ingredients. You are like a child.
When rapid improvements in the steam engine were made, so that according to you the so-called "Age of Steam" happened, uuuuh no! you ugly, piece of shit, n ☻ g g ☻ r, those were just substituting some components and design patterns for other components and design patterns and the result shown in power output statistics were just about the same (after substituting some numbers).
Are you retarded? Goddam this is what happens when you don't read real theory
like Adorno and Pitchfork.
