everything is a cause and effect reaction, new inventions lead to the technology of the future, and even as the generations of the past are slowly forgotten, their influence lives on to this day, affecting how the world eventually turned out and how it will be for generations to come. if I was able to help you, even in the slightest way, this could push you to continue with scratch and not give up after the program crashes, and maybe one day learn other programming languages and change the world. so, even if you don't remember my name, if I was able to help awnser your question, that is enough. going back to the example of toasters, do you know off the top of your head who invented them? no? have you used one? probably. you can make the world better, even if you don't know yet. are we but a blip on the timeline? sure, our names may not be remembered, but that's not the point. AII toasters toast toast, but what happens when there are no longer toasters being produced? will their technology simply become obsolete, with humans moving onto bigger, better things? will toast become a distant memory, written in textbooks of the future as foods us simpler generations ate? who's to say! society is constantly moving, changing, evolving, ideas being built upon, improved upon, theories being proven or disproven.
