Need of Amendment to DMCA

According to Article 512 of DMCA, an internet service provider could be immune from copyright infringement if it takes down internet contents upon receipt of infringement notice from copyright owner. However, it is time to amend Article 512 of DMCA in that it has given too much burden to copyright owner as well as it does not keep up with the current development pace of internet technology.
Such a monitor by copyright owner might be possible in 1998 when DMCA was passed since the number of internet users was not so many at that time. However, today, around one billion people are using internet all over the world, and thus, the uploadings made by these internet users are beyond our imagination. It is almost impossible for copyright owner alone to control illegal uploadings. I think that it would be desirable to amend Article 512 of DMCA in a way that the internet service provider such as YooTube shares such monitoring or controlling responsiblities with copyright owners. For example, Congress might consider charging internet service providers with obligation to set up any potential technical systems to prevent copyright infringement.
Some pelple argue that free flow of ideas or information is helpful for creative works and this freedom prevails copyright protection. This can be true in the early stage of any artist works. However, we should think that any artist would expect economic compensation for his work once he got wide attentions from outside and became famous. Without such compensation, any artists would lose their interests in further creative works. Better protection for copyrighted works would bear better fruits in the long run.
