Replace 'major labels' with 'VCs', 'Justin Bieber' types with 'social media apps', and 'file sharing' with 'app store' and you will see the situation is no different with start up's either.

Most start ups that get funding are websites and apps. How many medical electronics, water supply, waste management etc and software of real world value get funding?

Investors are going to put their money in places where they think they would get quick returns. Not the ones that are good for the world.

And this is not that difficult to understand.
