Originality and plagiarism seem to be completely different, but actually in some cases, it can be really hard to tell whether the work was plagiariased or it's just a coincidental resemblance. In today's world, the creators are making stuff including their own personal experiences and asking questions that a lot of people tend to ask or experience in their lives. Every artist is creating the art about something: specific genre, type, look because someone or something has inspired him. In the articles that I read, or the documentary I watched, every artist or person presented the story with the main thing that interested him. Then, they had to deal with other people who were also interested in the same thing. In the result, there was an issue because everyone wants to be the first, the best, the greatest, the true, the real, the acknowledged one. And though it might wouldn't seem so, that perfection everyone seeks also justifies the reason why the artists should be let to incorporate other peoples' work in to their art. Because other's art is also an experience, and in a lot of ways, that unoriginality is not intentional.
From my personal experience, I know that it's not fun when you have to face the "stealing" or the "borrowing" from your own work. When I was working on my project, and a good friend of mine didn't steal it, but presented some of the elements very similar to the ones in my work, I was upset. I was sure that the person didn't do it intentionally, and I knew that my idea was not the most original one, however, the fact that it was very similar in some ways started to rise the questions for me. Moreover, the same exact person decided to produce the project in the exact same place where I had decided to do it before hand. That rose into a bigger discontent of mine. It took a couple of weeks for me to let that go because I knew that it's going to be the reason when both of our works will be compared by the others and I will be put in the position where I will not voluntarily have to compete with my friend. After a long thinking, I came to conclusion that it's not worth it. Be who you are, follow what you believe in, and if someone borrows from you, be happy because you were that inspiration to someone. Maybe you won't get the credit, and maybe someone else will be awarded for your originality, but the value of art is not in the money, or recognition. Personally, I believe that true artist makes art for others to achieve the internal satisfaction. The admiration, the evaluation, and the fact that someone already adapted your idea for their own work, show that your work is good. Someone is admiring and wants to make the art like you do. My conclusion was based on that, and my other personal beliefs that I have about life, but whining and complain is definitely not the best thing to deal with that.
In terms of derivative borrowing, this is a short gap between a theft and originality according the authors of article. I would agree on that. If a person has an intentional wish to use someone's work as their own that would be the same as stealing. It's hard to proof it, but the difference would be obvious. In a plagiarized work there wouldn't be any new additions.
Our lives are full of borrowed ideas and it's not that "borrowing" and "stealing" happens in just visually or through sound. The fake Ray-Ban glasses sold of 15$ at the flea-market could be an awesome example of a transformative borrowing. Or a complete opposite one: a home cook, making a cake from some recipe found on the internet in some way is borrowing the idea. Overall, it is even hard to gasp the extent of types of plagiarism among us.
Personally, I also get a lot chance to incorporate someone else's work into mine. The music for the movies I make is a great example. I wouldn't be able to do it on my own, but the great websites on the internet gives an awesome solution. Another story would include the found footage I needed for Poetry video. The poem talked about a collapsing house, but there was not possible for me to capture it. I easily found the footage and used it for my own project that turned out well just because of it.
But taking everything into account, I could really ask a question about the authorship? It's hard to define, but actually if you didn't do a thing without anyone's help, you are already collaborating. Even if you borrowed the idea, or took the material from some project, you are already doing it with someone else I would agree with the idea that it's worth to be credited.
Overall, it's a tough thing to deal with, however, in today's world you have to understand that if your work is out there, it's a chance that someone will find it and will use of its own purpose. We won't be able to change that, and I think the industry and the sharing networking will continue to grow. There has been a huge progress in a solving the question of the sharing rights, but it's still a long way until the conclusion is drawn. I would say yes to the punishments for a voluntary plagiarism, but a strong no for the things that continue to spread the beauty of art into our world.
