I can't think of a better "take the moral highroad" solution to the problems created by the MAFIAA and IP in general than to simply create our own content, independent of their little bubble of crap. And the awesome news is that there's a lot of room for improvement in current content creation tools. There's just so much we can do to reduce cost and time to produce multimedia content. We have so many technology that are barely being touched by current tools. Because they're stuck in their incumbent sluggish giant position.
And that's where startups come into play! We have no ties to old incumbent technologies. We're free to innovate and completely re-imagine how content is created. Look at what wordpress made for publishing websites. Today any random non tech person can say "hey, I just had an idea, let me make a website about it". Imagine if you could say the same for movies "hey, I just had an idea, let me just make a full AAA movie about it really quick". The Valve filmmaker is incredibly in the right direction. But it's not even at 1% of where we can go.
Do you want to kill Hollywood? Then build awesome tools that allows anyone to build their own content!
