"My thesis is that Ethereum - being a world computer - is no different from other computers. It doesn’t need one app targeting 1 billion users. What Ethereum needs is 100s of apps targeting 100k-10 million users." This is exactly what is needed at this time! The Ethereum ecosystem doesn’t need to focus on creating a single 'killer app' for mass adoption. Instead, it needs a variety of apps for different niches and communities.
